My lower abdomen hurts on the right side, bulges a little, and my butt-hole itches; what is going on?

I've gone through series of seeing doctors, and they started with it being an inguinal hernia; but, then I got an ultrasound and there wasn't a hernia. I think I may have worms. I've had this problem for almost a couple of years. I need to fix whatever is really going on. I had anal intercourse and oral sex with some people around the time these symptoms popped up... I also get hungry rather quickly; an oral surgeon told me I may have some neurological problems... my nails have ridges... I always feel weak and/or tired... my lymph nodes in that area are swollen... **** my life...
