There is a numb skin on the back of my foot, what is going on?

If numbness occurs on the dorsum of the foot, and it is localized, this may be closely related to local neuritis. There are many reasons for local neuritis. If you are a diabetic patient, you should pay attention to this. This may be caused by complications of diabetes. You should go to the hospital for a careful check to see if your blood sugar is too high. In addition, you can also use some nerve nourishing drugs such as vitamin B1 for treatment.

There is a numb skin on the back of my foot, what is going on?

1. Poisoning: such as heavy metals such as lead, arsenic, mercury, phosphorus, drugs such as furacillins, isoniazid, streptomycin, phenytoin sodium, carbamazepine, vincristine, and organic compounds such as organophosphorus pesticides. 2. Nutritional metabolic disorders: such as vitamin B deficiency, diabetes, uremia, chronic gastrointestinal diseases, pregnancy, etc. 3. Infection: It is often accompanied or secondary to various acute and chronic infections, such as dysentery, tuberculosis, infectious hepatitis, typhoid fever, mumps, etc. In a few cases, it may be caused by direct invasion of peripheral nerves by pathogens, such as leprosy neuritis.

Performance

1. Sensory disturbance: In the early stage, it is often characterized by abnormal sensations such as burning, pain, numbness, or hyperesthesia at the finger (or toe) tips, and gradually the sensation decreases or even disappears. The distribution of sensory disturbances is glove- or stocking-like. A small number of patients may have deep sensory impairment. There is often tenderness in the gastrocnemius muscle and other places. 2. Movement disorders: manifested as decreased muscle strength, low muscle tone, weakened or disappeared tendon reflexes. In some cases (such as furazolidone), the reflexes may be active. Muscle atrophy may occur after long-term illness. 3. Autonomic dysfunction: cool, pale, flushed or slightly cyanotic skin on extremities, little or excessive sweating, thinning and tender or rough skin, loss of normal luster and increased keratinization of nails, etc. Due to different causes, the symptoms of the above three groups may be different. If it is caused by furazolidone poisoning, arsenic poisoning, etc., the pain is often more severe; if it is caused by diabetes, muscle atrophy is sometimes more obvious. The severity of clinical manifestations varies. Mild cases may only cause pain and numbness in the extremities without sensory loss or movement disorders, while severe cases may also cause limb paralysis. The prognosis is generally good. Recovery usually starts from the distal part of the limb.
