Suggest Treatment For Elbow And Leg Pain

Hi. I slipped and fell two weeks ago. I landed on my left side and at first only my elbow and left leg hurt, but they are better now. Now my back, kind of in the middle, and my right leg (groin area, feels like a pinched nerve) started hurting. I have not seen a dr. yet. Should I go to my primary care physician or to my chiropractor??
