Hello, I suspect it may be caused by herpes zoster virus it can be shingles. It would be necessary to see a photo before deciding diagnosis.  I think you can use calamine lotion over them. Also, you can take antihistamines for itching. You can use acyclovir to prevent spreading more pimples.  Hope I have answered your query. Let me know if I can assist you further.
