Lichen Planus

The cause of lichen planus is unknown, but is often attributed to an allergic reaction. This common rash appears in the form of single or clustered skin lesions. Over the counter antihistamines and topical ointments may help mild cases, though more severe rashes may require corticosteroids or ultraviolet light therapy. A biopsy may be required to confirm diagnosis.

Shingles are caused by the same virus (varicella-zoster virus) that causes chickenpox. Once a person has had chickenpox, the virus remains dormant in her system. For reasons that aren't completely understood, the virus can reactivate and cause a painful condition known as shingles.

The pain can be felt before any sign of the rash, but the rash is characterized by:

  • Burning pain
  • Small blisters on a base of inflamed skin
  • Band-like rash pattern on one side of the body
