I have skin pain that has no visible cause. what are risk factors for recurrent shingles?

Many possibilities: Recurrent zoster is unusual but not unheard of. You need to be examined, because there are other, more likely possibilities, such as infection and a nerve disorder. Pain should always be taken seriously; it's your body crying for help. See your doctor.

Recurrent shingles: According to the 2008 edition of "harrison's principles of internal medicine, " recurrent shingles results from deficits in cell-mediated immunity, the same problem that people with aids have, and, sometimes, inability to make sufficient antibodies. The two processes are usually linked because antibody production depends on communication between t-cells and b-cells of the immune system. See doctor.
