If you are in pain and do not know the cause, you should seek medical help. I can't respond to whether your symptoms are typical of prostatitis, but if I had those symptoms, I would want to know what I could do to relieve them. If it is prostatitis, you should get it treated rather than accept the pain. And if it is something else, you need to find that out as well. You might want to visit a different doctor to get a fresh evaluation.
