Prostate Pain?

Hi guys.

Im pretty sure Ive been experiencing some kind of prostate pain for quite a while. For since I was about 18-20 Ive been occasionally feeling pain from the rear left pelvic area to just under the lower left ribs. At first I used to think it might have been some kind of muscle strain. I used to feel it most when I played pickup basketball without much of a warmup and I would be limited physically by the pain.

It isnt excruciating pain but its almost like a groin pull whereby I couldnt extend the leg in some angles or I would get a sharp pain. I really hope this is muscle related but Im beginning to suspect the prostate. (fingers crossed)
