Not sure, Some people get folliculitis ("clogged pores") for no apparent reason. These may look and behave like your spots. Eventually, they just peter out and go away. Bugs are unlikely if your husband hasn't got any. You might try Sarna lotion for itch (non-Rx) to tide you over.
Best.

I have it now and I think my younger son has it too. Please help.
