I have dealt with pain, swelling and numbness beginning at left buttocks and extending down left side of leg and ending at foot. As we speak, my left calf, ankle and foot are almost twice size of right. this has bothered me for about 2 years, with consultations with orthaepedic surgeons and pain management specialists. I have had X-rays and MRI s done, but no one has actually said what is causing problem. Over the years, I have been injected with steroid shot to relieve pain. This will work for about a month. Doctor now says he will not issue any more shots. What next?
