I have just noticed red and white patches under the skin of the head of the penis while i was masturbating. I am currently using a antifungal cream because my GP seems to think that i have Thrush but the cream isnt making any difference. The whole of my penis and each side of my scrotum is red and sore and itching but went away with a once treatment antifungal oral tablet. blood and proteins have been found in the blood and STI/STD tests came back negative, it felt like my prostate blew up like a balloon and i couldnt pee or pass stools, (got to the point where i had to physically push them out) in the early stages 2 months ago i urgently needed the toilet and hurt when my bladder filled. was given both Doxy and UTI meds both didnt work. can you help
