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 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. 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.
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, which is caused by excessive alcohol intake. 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.
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. A stroke or mini-stroke can sometimes cause temporary or long-term numbness in parts of the body. 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:. 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.

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

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. 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. Medicines that cause numbness or tingling may need to be switched or changed.
DO NOT change or stop taking any of your medicines or take large doses of any vitamins or supplements until you have talked with your provider.
Because numbness can cause a decrease in feeling, you may be more likely to accidentally injure a numb hand or foot. Take care to protect the area from cuts, bumps, bruises, burns, or other injuries. If you have chronic numbness of the feet such as from diabetes , seeing a podiatrist regularly can help prevent complications.
Your provider will take a medical history and perform a physical examination, carefully checking your nervous system. You will be asked about your symptoms. Questions may include when the problem began, its location, or if there's anything that improves or worsens the symptoms.
Your provider may also ask questions to determine your risk for stroke, thyroid disease, or diabetes, as well as questions about your work habits and medicines.

They work by squeezing the veins and muscles in the leg, which helps to improve blood circulation in the legs and reduce swelling. It is characterised by an abnormal immune response that targets myelin, a fatty material responsible for insulating the nerve fibres in the central nervous system. This causes the disruption of nerve impulses.
This causes delays and changes to the signals being transmitted between the nerves and the brain.
