Three weeks ago I had an oral surgery and the doctor prescribed me penicillin for 10 days. On the second day I started to itch and I knew I had a yeast infection. I consulted a doctor and was told that it would not help to prescribe the diflucan until I was done with the meds. One week ago I took the diflucan and now I have a sore by my peritoneum, I am so scared because I dont want to have genital herpes. I never had this happen before. When I had the yeast infection it was very bad and my vagina and by my anus was very itcy, red and sore. I am still having a little discharge but the itching is gone. I think that the sore came from the yeast infection. Do you have any insight on this. The sore is painful and it burns when i urinate
