It’s been a month since I have had these rashes and now I am damn sure I have genital OB. I am getting very paranoid because of these rashes. I have a major rash on my arms but my STD specialist and dermatologist could not identify that the genital rashes were due to herpes. I do not know if the arm rash is related to herpes. They are tiny tiny blisters in appearance. Can anyone please give me an opinion about the same?
