Hello,
It is good that the STD panel has come out all clear. However it is important to rule out HIV and confirmation is only done by specific tests for HIV like western blot,PCR and ELISA.These tests may show accuracy after 6 weeks to 6 months as HIV antibodies take time to develop in the body. So get it done after 6 months also. Other than that it can be simple irritation of the skin.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
