Hi every one I have had PMR for 8 years am now down to 3.5pred for the second time so I have my fingers crossed. However I have been getting a lot of knee pain. can only walk for about 10 mins and pain kicks in . I have seen orthaepedic doctor had xrays and scan which only show wear and tear and some osteoathrites . I saw a physio last week he said it is cartlige problem and has given me excercies to do, he said it needs to be much worse before NHS will do clean up job. I am not sure which way to go at the moment I have taken pain killers including tramodol but nothing seems to help .I am doing physio excercises maybe it will improve has anyone got any more advice or had same problem .I hate not doing my daily walks.
