I had anterior hip surgery a month ago, Initally terrible burning in operated thigh. I was put on lyrica, Celebrex and pain pills. Ther terrible is better but now I have discomfort burning and numbness and some on and off pain in both thighs. Did something go wrong or could it be part of fibro, possible diagnosis years ago. Anyone with this,please respond, thanks
