Hi, I have strange white plaques in and around my urethra. They first appeared after I used vaginal vitamin C tablets and a second time, five months later, after I drank a lot of cider. Now they are there all the time. They look like lichens and have an unpleasant smell. I peel them off daily with tweezers and they grow back in about 6 hours. They stop growing during the night. I tried anti fungal creams and oral treatment and there is no effect. I took doxycycline and nothing happened. After I took trimethoprim the condition got worse. I tried using tea tree oil and they grow out of control. I've seen five doctors and they don't know what it is. I searched everywhere online. Please give me some advice.
