I am just over 3 weeks post op from having a left hip resurfacing. When I was at 2 weeks, the cramping in my left thigh was pretty unbearable, and now at 3 weeks it does seem to be subsiding. Why did you have to have the surgery? My problem was congenital hip dysplasia - and, I believe my cramping is due to my muscles having to readjust to a corrected leg length and learning to walk normally. I also had large amount of bruising the back of my entire thigh that extended to the calf of my leg. My instructions are to use crutches for 6 weeks - and, with the cramping pain I had at 2 weeks, I know I would not have been able to walk without the crutches. Walking with crutches helped to "walk out" the cramping. Currently, I do a position change hourly to help reduce the amount of pain in my thigh - that, and elevating my leg as high as I can when I am sitting or in bed helps. My thihg will cramp initially when I sit or lie, but, if I just lie still for about 15-20 minutes, the cramping subsides. I agree with Pat to keep an open dialogue with your doctor - he will not know what you are dealing with at home, unless you call and tell him. Do not worry about being a pest - the more information you can give him the better he can help you. I know - I am a RN.
