Whenever you feel numbness in any part of your body, it is a sign of disturbed innervation or blood circulation in that specific area. However, the reasons for these disturbances are numerous. People are particularly afraid of the numbness in different areas of the head, so here are some of the most common reasons which can cause this unpleasant sensation.

Herpes Zoster

Herpes Zoster is an infection caused by the Varicella Zoster virus. This is actually a reactivation of the virus, which was preserved in the nerve cells after primary infection (chickenpox).

Symptoms of herpes zoster include an uncomfortable feeling in the affected area, such as numbness, itch, and irritation, which then progress to pain. Blisters and redness also appear on the surface of the skin. What is very specific for this disorder is the presence of signs and symptoms only on one side of the body. It is very rare for both sides of the body to be affected. These skin changes can last for several weeks, and numbness and pain are in some cases prolonged, even weeks after the disease subsides.

Diabetes Mellitus

In persons with diabetes mellitus, various sensations on the skin surface are not unusual. Pathological processes occurring in the scope of this disorder damage small nerves and blood vessels, thus producing vegetative skin changes, such as hair loss, dry, tightened, and fragile skin). Neurological sensations include numbness, and insensitivity to touch and pain. These symptoms can be prevented by keeping optimal blood sugar levels. Luckily, in most persons with diabetes, this is possible to achieve using oral antidiabetics and/or insulin, but discipline is also very important.

Mechanical Nerve Damage

Mechanical damage to sensitive nerves can also be responsible for the feeling of numbness in different parts of the body. Prolonged pressure to the nerves in the upper neck area can cause numbness in the same side of the head. As many of you know, the nerves recover very slowly, so it will take several weeks, or even months until the feeling is back. Recovery can be stimulated by taking vitamins that are important for the nervous system, such as B6, B12, and vitamin C.

Lyme Disease

Lyme disease is a bacterial infection caused by the spiral bacteria Borrelia Burgdorferi. It is transmitted by tick bite. It is very easy to cure Lyme disease by using antibiotics, but in case of not being cured, it goes through three phases. It may take years before the neurological symptoms of Lyme disease appear, and that is usually the third phase. The most common symptoms include memory problems, mood changes, numbness in the certain parts of the body, etc. If you suspect that you might have Lyme disease, please visit your doctor in order to perform laboratory tests and investigate this possibility.


Some forms of epilepsy manifest as partial attacks, which can be limited only to sensitive nerves. In that case, the only manifestations are unpleasant sensations, such as numbness, irritation, or pain in different body parts.

Psychological Reasons

Nervousness and stress can cause disturbances in the functioning of central and peripheral nervous system. Therefore, occasional numbness in different parts of the body can be caused by these disturbances. If you notice frequent numbness sensations, you should visit your doctor in order to perform a detailed investigation.
