B02.2: Zoster with other nervous system involvement
Shingles is caused by certain pathogens. These pathogens are viruses. These viruses also cause chickenpox. Once someone has been infected by the chickenpox viruses, the viruses remain hidden in the body for a long time. Sometimes the viruses may break out again after several years and cause shingles. Then, with shingles, small red blisters and pustules form on a particular part of the skin. The blisters and pustules usually stay in one half of the body and form a belt pattern. The part of the skin that is affected can be very sore. You can also get a high temperature and headaches and feel very sick.
Your nerves have been inflamed by the shingles. Many nerves run from the spinal cord and brain to the organs, skin and muscles in the body. When nerves are inflamed it can be very painful. The pains occur in areas where there are inflamed nerves. The pain can continue even when the nerves are no longer inflamed. You may also feel an unpleasant tingling or numbness.
