Was just on an airplane for 4 hours, now I have pain in my upper butt area and down both backs of my thighs; hurts to cough/ sneeze and go to the bathroom,also when I go to try and sleep, I have ringing in my ears and pressure in my head/ terrible head ache. Had an AVM removed about 10 years ago... should I go to urgent care or the Emergency room? Or wait til August 1st for my doctor to see me.
