Hip and Leg Pain After Tummy Tuck

I am 3 weeks today from my tummy tuck. 3 nights ago my hip started hurting when I put my leg strait. if anything rests on that portion of my leg I get a sharp constent tug that runs from my hip to mid way down my leg. I was almost walking normal now Im hobbling and upset because I thought I was home free. to top it off Im unable to really use the girdle because of my hip aches. my doctor says its a nerve. when will this heal and is there something I can do to speed the process up?
