I have a pain under my right hip that is taking the shit out of me. Saturday it was really bad and I barely could lie in bed on my left side, moving impossible, plus a low fever and bad diaerhea. Yesterday was better, walking around, no fever no pain. Today again, had to cry all morning with the pain and low fever is back. Should I go to the ER (not easy as have toddler)? I have a doctor's appointment tomorrow morning, should I wait until then? Please tell me what you would do.
