A person may feel numbness in their legs and feet due to sitting in a position that puts too much pressure on the nerves or reduces blood flow. However, long-lasting or unexplained numbness may be a sign of an underlying medical condition.

Long-term numbness or a tingling feeling in the legs and feet may be due to conditions such as multiple sclerosis (MS), diabetes, peripheral artery disease, or fibromyalgia. The sensation may be felt in the whole leg, below the knee, or in different areas of the foot.

In this article, we look at some of the reasons why a person might experience numbness in the legs and feet, along with symptoms and treatments.

Causes of numbness in legs and feet

Crossing the legs for a long time may cause numbness and tingling in the legs and feet.

Often, a person’s legs go numb temporarily because of their posture. However, chronic or long-lasting numbness in the feet and legs is almost always a sign of an underlying medical condition.

Conditions associated with feet and leg numbness include:

Posture

Postural habits that put pressure on nerves or reduce blood flow in the lower limbs are the most common cause of temporary numbness in the legs and feet. Many people say their leg has “fallen asleep,” and the medical term is transient (temporary) paresthesia.

Habits that can cause the feet and legs to fall asleep include:

  • crossing the legs for too long
  • sitting or kneeling for long periods
  • sitting on the feet
  • wearing pants, socks, or shoes that are too tight

Injury

Injuries to the torso, spine, hips, legs, ankles, and feet can put pressure on nerves and cause the feet and legs to go numb.

Diabetes

Some people with diabetes develop a type of nerve damage called diabetic neuropathy. Diabetic neuropathy can cause numbness, tingling, and pain in the feet, and if severe, the legs as well.

Lower back issues and sciatica

Problems in the lower back, such as a breakdown or herniation of spinal discs, can cause compression of the nerves going to the legs, leading to numbness or sensory disturbances.

Sciatica is the name for irritation of the sciatic nerve, which runs from the lower back to the legs. If this nerve becomes irritated or compressed, a person may experience numbness or tingling in their legs or feet.

Tarsal tunnel syndrome

Tarsal tunnel syndrome occurs when a nerve that runs down the back of the leg and along the inside of the ankle and into the foot is compressed, squeezed, or damaged.

The tarsal tunnel is a narrow space on the inside of the ankle. People with tarsal tunnel syndrome tend to feel numbness, burning, tingling, and shooting pain in their ankles, heels, and feet.

Peripheral artery disease

Peripheral artery disease (PAD) causes the peripheral blood arteries in the legs, arms, and stomach to narrow, reducing the amount of blood they can pump and reducing blood flow. The legs are one of the most common parts of the body impacted by PAD.

Most people with PAD experience pain and cramping in their legs and hips when they are walking or going upstairs. Some people with PAD also experience leg numbness and weakness.

Symptoms of PAD typically go away after a few minutes of rest.

Tumors or other abnormal growths

Tumors, cysts, abscesses, and benign (non-cancerous) growths can put pressure on the brain, spinal cord, or any part of the legs and feet. This pressure can restrict blood flow to the legs and feet, causing numbness.

Alcohol use

The toxins in alcohol can cause nerve damage that is associated with numbness, especially in the feet.

Chronic or excessive alcohol consumption can also lead to nerve damage that causes numbness. This type of nerve damage is linked to reduced levels of B vitamins, such as B-1 (thiamine), B-9 (folate), and B-12, which is caused by excessive alcohol intake.

Fibromyalgia

Fibromyalgia is a chronic or long-lasting condition that causes widespread body pain, aching, and tenderness. Some people with fibromyalgia also experience numbness and tingling in the hands and feet.

Most people with fibromyalgia experience a variety of symptoms including:

  • stiffness and soreness for no apparent reason, especially in the morning or after sleeping
  • chronic exhaustion
  • memory problems and difficulty thinking clearly, sometimes called fibro-fog
  • restless leg syndrome

Almost everyone with fibromyalgia experiences symptoms in more than one part of their body for at least 3 months at a time. If numbness in the legs and feet is not accompanied by any other symptoms or is not long-term, it is unlikely to be caused by fibromyalgia.

Multiple sclerosis

People with multiple sclerosis (MS) experience sensory nerve damage that can cause numbness in a small region of their body or whole limbs. Although numbness associated with MS often only lasts for a short period, it can last long enough to become disabling.

Stokes and mini-strokes

Strokes or mini-strokes can cause brain damage that may affect how the mind interprets and processes nerve signals. A stroke or mini-stroke can sometimes cause temporary or long-term numbness in parts of the body.

Symptoms

Numbness is just one of the many symptoms associated with temporary and chronic numbness.

Many people with numbness in their legs and feet experience additional symptoms at the same time or intermittingly, such as:

  • tingling
  • burning
  • tickling
  • itching
  • a crawling feeling under the skin
Treatment

The proper treatment for numb legs and feet depends entirely on the cause.

Medication

Medical options for long-term numbness in the legs and feet include:

  • Antidepressants. Some antidepressants, such as duloxetine and milnacipran, have been approved for the treatment of fibromyalgia.
  • Corticosteroids. Some corticosteroids can help reduce chronic inflammation and numbness associated with conditions such as MS.
  • Gabapentin and pregabalin. Medications that block or change nerve signaling may help reduce numbness associated with conditions such as fibromyalgia, MS, and diabetic neuropathy.

Home remedies

Home remedies that may help to relieve uncomfortable numbness in the legs and feet include:

  • Rest. Many of the conditions that cause leg and foot numbness, such as nerve pressure, improve with rest.
  • Ice. Ice can help reduce swelling that can put pressure on nerves. Apply cold compresses or wrapped icepacks to numb legs and feet for 15 minutes at a time several times daily.
  • Heat. Heat can sometimes help loosen stiff, sore, or tense muscles that can put pressure on nerves and cause numbness. However, avoid overheating numb legs and feet, as this may or worsen inflammation and cause pain and numbness.
  • Massage. Massaging numb legs and feet helps improve blood flow and may reduce symptoms.
  • Exercise. A lack of proper exercise can weaken the heart and blood vessels, reducing their ability to pump blood to the lower limbs. Activities such as yoga, Pilates, and tai chi can promote blood flow and reduce chronic inflammation or pain.
  • Supportive devices. Braces and specially designed footwear can help reduce nerve pressure caused by conditions such as injury, tarsal tunnel syndrome, or flat feet.
  • Epsom salt baths. Epsom salts contain magnesium, a compound known to increase blood flow and circulation. Epsom salts are available for purchase online.
  • Mental techniques and stress reduction. People with conditions that cause chronic numbness, such as MS and fibromyalgia, should try to focus on the fact that the periods of numbness are often short-lived and go away on their own. Stress also tends to make the symptoms of central nervous system disorders worse.
  • Sleep. Many of the chronic conditions associated with leg and feet numbness are known to worsen with a lack of proper sleep.
  • A healthful, balanced diet. Malnutrition, especially vitamin B deficiencies, can cause nerve damage leading to numbness. Getting enough vitamins and other nutrients can also reduce chronic inflammation and pain, which can cause numbness.
  • Alcohol reduction or avoidance. Alcohol contains toxins that can cause nerve damage and numbness. Alcohol also usually makes the symptoms of chronic pain and inflammatory conditions worse and can even cause flare-ups of symptoms.

When to see a doctor

Talk with a doctor about numbness in the legs and feet that:

  • is not related to postural habits or lifestyle factors, such as tight clothing and footwear
  • lasts for long periods
  • is accompanied by any other chronic symptoms
  • is accompanied by permanent or long-term changes in the color, shape, or temperature of the legs and feet

Numbness in the legs and feet is a common disorder, though when it becomes chronic, it may be a sign of an underlying medical condition.

Anyone who experiences numbness that is unexplained, persistent, frequent, painful, disabling, or accompanied by other chronic symptoms should see a doctor for a diagnosis and to discuss treatment options.

All About Foot Pain- Causes and Treatments

/in , , /by

Foot Pain

Feet. They carry you from here to there every day. But you may not think much about them until they hurt. And when they do, you want relief. To get the right treatment, you need to know the problem. The first thing to consider is where your pain is located.

Heel Pain

If your pain is in your heel, you may have plantar fasciitis. That’s an irritation or inflammation of the band of tough tissue connecting the heel bone to the toes. Usually, it hurts the worst in the morning when you’re getting out of bed. You can feel it in your heel or in your arch.

To treat it:

  • Rest your foot.
  • Do heel and foot muscle stretches.
  • Take over-the-counter pain relievers.
  • Wear shoes with good arch support and a cushioned sole.

Heel spurs are another source of foot pain. These are abnormal growths of bone on the bottom of your heel. You can get them from wearing the wrong shoes or from an abnormal walk or posture, or even from activities like running. The spurs may hurt while you’re walking or standing. Lots of people have them, but most don’t have pain. People with flat feet or high arches are more likely to have painful heel spurs.

To treat them:

  • Wear a cutout heel pad.
  • Use a custom-made insert (called an orthotic) worn in the shoe.
  • Wear shoes that fit well and have shock-absorbing soles.
  • Take over-the-counter pain relievers.
  • Rest your foot.
  • Try physical therapy.
  • If you still have pain, ask your doctor about medical procedures.

A stone bruise is a deep bruise of the fat pad of the heel or ball of the foot. It’s often from an impact injury, but it can also happen after stepping on a hard object. The pain feels like you’re walking on a pebble. It will gradually go away on its own.

In the meantime:

  • Rest your foot.
  • Ice the area.
  • Take over-the-counter pain relievers.

A heel fracture is usually a high-impact injury such as from a fall or car accident. Your heel bone may not just break, it could also shatter. Heel pain, bruising, swelling, or trouble walking are the main symptoms.

To treat it:

  • Don’t put pressure on the heel. You can use crutches.
  • Protect the heel with pads.
  • Wear a splint or cast to protect the heel bone.
  • Ask your doctor about over-the-counter or prescription pain relievers.
  • Try physical therapy.
  • If you’re still in pain, ask your doctor about surgery.

Ball of Foot Pain

Metatarsalgia. You feel this pain and inflammation in the ball of your foot. Ill-fitting shoes are the usual cause. But you might get it from strenuous activity, such as running or jumping. It’s sometimes called a stone bruise as well.

To treat it:

  • Take pain relievers.
  • Ice and rest your foot.
  • Wear comfortable footwear.
  • Try shoe inserts to relieve pressure on the ball of your foot.

Morton’s neuroma causes a thickening of the tissue around the nerves between the bases of the toes (usually between the third and fourth toes). You typically feel pain, odd sensations or numbness over the ball of your foot. Women have it more often. It can be a result of wearing high heels or tight shoes.

To treat it:

  • Wear shoe inserts to reduce pressure on the nerve.
  • Get a steroid or other injection into the foot.
  • Take pain relievers.
  • Don’t wear high-heeled shoes or ones with a narrow toe box.
  • Avoid activities that put pressure on the neuroma.
  • Ask your doctor about surgery.

Sesamoiditis. Near your big toe are 2 bones that are connected only by tendons. They’re called sesamoids. You get sesamoiditis when the tendons surrounding them become injured and inflamed. It’s a form of tendinitis, common with runners and ballet dancers.

To treat it:

  • Rest your feet.
  • Ice where it hurts.
  • Wear a foot pad under the toe in a comfortable shoe.
  • Tape the big toe to immobilize the joint and allow for healing.
  • Wear low-heeled shoes.
  • Ask your doctor about steroid injections.

Arch Pain

Plantar fasciitis. This is the most common cause of arch pain. Plantar fasciitis can affect the heel, arch, or both. Treatment is the same regardless of the location. For persistent plantar fasciitis, an injection with a mixture of a steroid and local anesthetic can be helpful.

Fallen arches , or flat feet, happen when the arches of the feet flatten out (often when standing or walking), causing foot pain and other problems. Flat feet can be treated with shoe inserts, shoe adjustments, rest, ice, using a walking cane or brace, or physical therapy. Sometimes surgery is necessary.

Toe Pain

Gout , which is a form of arthritis, can causes pain in the toes. Crystals collect in toe joints, causing severe pain and swelling. The big toe is often affected.

To treat it:

A bunion is a bony bulge along the edge of the foot, next to the base of the big toe. It’s associated with misalignment of the first toe joint. Anyone can get them, especially if they wear ill-fitting or uncomfortable shoes. It often shows up as people age. People with bunions often also have hammertoes as well. Try changing to more comfortable shoes or wearing shoe inserts. If you’re still in pain, your doctor may suggest surgery.

A hammertoe is when your second, third, or fourth toe bends at the middle joint, creating a hammer-like appearance. It can come from a muscle imbalance, but it can also be brought on by wearing ill-fitting shoes.

Your doctor will likely recommend you wear shoes with a wide, deep toe bed. She may also give you exercises to stretch your toe muscles. If you still have problems, you can talk to your doctor about surgery.

Claw toe is when your toe points down or up and is unable to straighten. It’s often the result of nerve damage from diseases like diabetes or alcoholism, which weakens the muscles in your foot. Without special footwear to accommodate the claw toe, you may develop irritation and calluses.

To treat it:

  • Change to better-fitting footwear. Avoid high heels and tight shoes.
  • Do stretches for your toes and toe joints.
  • Try shoe inserts.
  • Ask your doctor about surgery.

An ingrown toenailis when skin on one or both sides of a toenail grow over the nail. It can be painful and may lead to infections.

To treat it:

  • Soak the foot in warm water four times a day.
  • Once daily, wedge a piece of gauze between the nail and wet skin.
  • If these treatments don’t work, see a doctor.
Turf toe is when you feel pain at the base of the big toe. It’s an overuse injury usually caused by strain. Turf toe may also be a form of sesamoiditis or a sesamoid fracture.A toe sprain may happen when you jam or stub your toe, damaging the tendon or soft tissues of the toe. If you don’t have a fracture, the pain and swelling should go away within days.A toe fracture, or broken bone, can happen in any of the bones of the toes. Minor fractures may only require rest, ice, and pain relievers. Serious fractures may need surgery. Go to a doctor to be sure.

Hallux rigidus (stiff big toe) is a type of arthritis at the base of the big toe. Symptoms are pain and stiffness of the joint that worsens over time. Treatment can include pain relievers and stretching exercises. Surgery may be needed in some cases.

Corns and calluses. Corns are thick buildups of tough skin on a point of irritation or pressure on the foot or toe. They sometimes look like horns. Calluses are wider areas of tough skin buildup on the toes or feet. They happen as a result of irritation or pressure. Calluses and corns are generally caused by poor-fitting footwear.

To treat them:

  • Wear better-fitting shoes.
  • Soak the foot and use a pumice stone to wear down the extra skin.

A sesamoid fracture is a break in the small bones (sesamoids) that are embedded in tendons attached to the big toe. Pain in and around the big toe is the main symptom.

To treat it:

  • Rest, ice, and elevate your foot.
  • Wear stiff-soled shoes or foot pads to relieve pressure.
  • Take pain relievers.
  • If you’re still in pain, talk to your doctor.

Pain on the Foot’s Outer Edge

The outer edge of your foot, the fifth metatarsal bone, is a commonly broken bone in the foot. Pain, swelling, and bruising along the outer foot edge after an injury are symptoms. If you think you may have broken a bone, see a doctor and have an X-ray.

To treat it:

  • Take pain relievers.
  • Rest, ice, and elevate your foot.
  • Don’t walk on it.
  • Ask your doctor if surgery is necessary.
  • A cast may be necessary in some circumstances.

Foot Pain That’s Anywhere or Everywhere

Neuropathy, or nerve damage in the feet, is most often caused by diabetes. The pain can be burning, stinging, or feel like electricity. It can happen anywhere in the feet. Ask your doctor about pain relief options and ways to prevent further worsening.

Tendinitis is inflammation and irritation of tendons, the bands attaching muscles to bones. Tendons run along all the surfaces of the foot and can cause foot pain in many different locations.

To treat it:

  • Rest your foot.
  • Take pain relievers.
  • Steroid injections can help.
  • Surgery is rarely needed.
