Perineal Pain

Since sunday (4 days ago) I have noticed a slight pain in the perineal area. It was barley noticable sunday and now is a bit worst (pain scale 2.5/10). First off let me tell you I am terrified of doctors and that would be a last resort. I am a 18/male in good health. I have no problem using the bathroom and nothing is painful to the touch. Just a dull pain in that general area. I have looked this stuff up on many sites and the closest things I could see was prostatitis. The only problem is I only have that pain and none of the other symptoms! It goes away overnight and feels fine untill I get up and about for a few minutes then it comes back.The only real problem this is causing is the "uncomfortable pain" (not even that bad) and me getting worried. I slept 15 hours last night because I dreded waking up and having to worry about this again.

How long do you think it is safe to wait to see a doc?
What would they do if I went?

Now I am not dumb and if it gets to the point where it is very uncomfortable I will go but I can't see my self going for this right now.

Thanks in advanced!
