Sounds like you need a urologist. I don't know what it is, but it could be vascular. Make the appointment today and describe it and try to get in quickly, just in case.
Hello,
Excessive manipulation can sometimes lead to pain. Other causes are balanitis, prostatitis, bladder neck stone, urethritis, herpes, peyronie’s disease or penis cancer. Get all these causes ruled out from a urologist.
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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
