Suggest Remedy For Pain After Hip Replacement Surgery

I am 61, had hip replacement end of September 2014, completed therapy and all was going great..Joined gym and started work out regimen at place where I took therapy... the thigh muscle, where hip was replaced started giving me shooting pain.. sometimes radiates all the way to my foot.. tried ice, message, etc.. at first if I made sure I was walking with toes pointed forward it would quit hurting, but last few days that hasn t worked and outer thigh especially hurts when walking.. Wondering if I shouldn t just call the surgeon that did my hip or go to general doctor to see what s going on
