I have chronic pain in my left knee with regular water retention. I attend the pain clinic they are doing injections in my left hip. I have had 2 knee operations as the surgeon said just tidying it up. He says there is no sign of arthritis but he was going by my last xray 6 years ago. I also suffer with my feet they are numb and tingle constantly feeling cold. Cant walk far due to the pain. Is this arthritis should I demand another xray?
