I have gone to the doctor so many times and they can't figure out why my back left side is hurting so much. I have recently delevoped a very painful pain in my left side front which is bad I am having trouble walking. Can you suggest some test they can do besides MRI. I was thinking of an ultrasound. I have also had a urine infection for over 3 weeks now and they can't seem to help me. I have been on antibotics 3 weeks now and have taken three diffent ones. Please help!!!
