Hi, So this started happening since I was a teen. I used to have these flare ups after w#nking that used to go by itself after like 15 mins. This used to happen rarely and mostly after wa#king. Got tests done for all kinds of transmitted infections and urine culture. All negative. Ultrasound of prostate came in normal too. 10 years have passed and now the pain happens by itself. It starts when I am sleeping at nights and the sensation would wake me up. The sensation runs from the tip of my P$nis to the bottom of my toe. After 15 mins I feel an urge to go washroom. I sit in washroom and pain increases as I urinate. I try to empty my bladder completely and come back to bed. Then pain then starts subsiding gradually. I also notice some sort of scum/foam when i urinate after this sensation. I am not sure if this is some kind of prostatitis, pelvic floor disorder, UTI or nervous issue. I feel depressed and helpless. Any clues what it can be ?
