Shingles?: Ask your doctor to check . If they are confined to one side and are painful, I would suspect shingles. Early treatment with an anti-viral drug may reduce the duration of the disease and its complications.

Tricky: Without an actual examination, I cannot give specific medical advice on your particular health, Dermatologic conditions are hard to evaluate without seeing them. But one spot implies a local cause: Inflammation/infection from specfici exposure or bug bites come to mind
