HELP!

I went bowling last night and at about the 8th frame my entire left side from my groin down started hurting so bad I had to sit down. When I went to the bathroom I waddled all the way, and couldn't sleep at all because of the pain, and because baby wouldn't sleep (she normally does)

Should I see a doctor or rest up more and see if it goes away?
