I am 7 weeks post total hip replacement and walking un-aided. I have developed a weird nagging ache in both legs where i feel i want to stretch my legs about a 100 miles. I take diclofenic and co-codamol which does help but really want to kick the meds. Alot of the nagging ache collects around the knee. Its worse sleeping and does wake me up. Its so annoying as i really have recovered well from the operation. Sometimes I feel its nerve pain or sometimes muscle I dont know. Is anyone experiencing the same? Thanks.:-)
