Thank you Dew & Pete - I was just so frustrated the other nite after the appt - had my hopes up for help and feel let down again. I do have a Pain Management dr - for about 1-1/2 years and problem I have is that it is just pills he wants to issue (I do appreciate the pain medication!) and not help me in the rehab dept which I drastically need. I have had my knee reopened since the original knee replacement and RSD diagnosis. They did keep me in the hospital longer and gave me the precautions needed so the RSD did not spread or go into a flare thank goodness. I had no RSD problems from this surgery - but it did not go away either. Right now my main complaint is I do have RSD but the recent pain I am feeling is not RSD driven from what I feel. I really believe something else is wrong in the knee area - whether a cyst or whatever. Thank you Dew for the link to the cyst - it explained alot more than the dr did. As for the Pettella problem - I did have problems with this - but that is what brought on the total knee replacement so have all new hardware of a knee. With my knee giving out and me falling down so much and with this new type of pain, I'm not sure what to think and that was the reason I went to the new ortho. I realize many have problems getting the RSD diagnosed and go many years trying to do so. My problem is the physicians know I have RSD and are too quick I feel to state that everything is from the RSD instead of researching that it could be something else wrong also besides the RSD. We all have different stories about our RSD I guess - but we all have it change our lives drastically! Thanks again for listening.
