Anal Pain

So I've been pretty anxious about a sudden pain around the anus one day when I defecate. I haven't had this before and it doesn't seem to be getting worse (It got better after a few days but it's still here), I don't see any blood on my stool either. It's not painful but rather uncomfortable right after I pass solid stools. Right before I had this I worked out a lot and do a moderate amount of stretching, and normally it would sweat a lot down there. I really doubt it's hemorrhoids but I'm getting anxious that it could be worse.

Sounds like piles and/or a tear/fissure

Will it heal on its own? I can't see my GP atm, it doesn't seem to be anything major so I don't think rushing a check up is necessary.
