I have recurring skin rashes in different areas that appear like fever blisters or shingles and itch. i never had chicken pox. it lasts a couple wks. ?

Herpes?: It hard to tell what you have that return in different areas and itch - not likely zoster maybe allergic reaction herpes simplex maybe ...See a doctor for a diagnosis.

Chickenpox: Chickenpox is not a rash that keeps recurring. A rash from Chickenpox often occurs first on trunk (chest/back) & then moves to face & then extremities. The rash becomes blisters that itch. Blisters usually have all transformed into scabs in about a week. Your doctor may be able to shed light on the cause of your recurring rash.
