Hello,
Definitely from your symptoms STD’s need to be ruled out. The only way of ruling it out is by getting yourself tested for genital herpes. Laboratory tests include: culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction (PCR) to test for presence of viral DNA. I sincerely advise you to consult a dermatologist and get it ruled out.
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 dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Yeah you should go to the drs to be tested, herpes is a skin to skin contact STD so unfortunately even a condom can't guarantee you wont become infected. The surrounding skin is also affected. I hope you end up being alright hun.
Given the symptoms, you may have an STD, a vaginal infection, or trochomoniasis, all of which need prescription med to cure - visit your obgyn.
