I went to an emergency room last night and was diagnosed with a kidney infection, and possibly had passed a kidney stone. The pain was located in my left lower back, around to the front of my abdomen and down the thigh of my left leg. I started antibiotics and the area around my kidneys isn t hurting as badly, however the front of my thighs is still excrutuiatingly painful. When I walk, stand and particularly sit. It Is like a knife poking in me. Could this pain still be from a kidney infection. Thank you
