i had a revision hip replacement in january this year ,after coming off my crutches i started to get pain in the middle of my thigh i just put it down to my recovery but the pain has got worse more so after resting i have just been back to the hospital and my x rays have come back normal so the doctor requestsed blood tests thinking it might be abone infection he has told me to come back in 2 months for the results but im really worried is there anything else this pain could be and what will happen if it is a bone infection
