What is causing my pain and symptoms. I had a hip replacement one year ago. I have pain in the groin and inner and outer thigh. I can't raise my leg (the leg I had the surgery on) without pain. When I get in and out of the car, I have to grab my pant leg and pull my affected leg up just to get in or out of the car. I have a cyst on my kidney and I have mid pelvic calcification. I had a 24 hour creatinine clearance test and that was very low. I also have protein in my urine. I am anemic, also. What is going on? All of this since my surgery.
