I've had the pain in both knees but it's mostly my left knee. If I don't move it for awhile I get horrible pain when I do. Almost like everything tightened up and doesn't want to stretch. I have to do "labor breathing", short, quick breaths to tolerate the pain. Once I am through that, it's just a dull throb. I had it happen in my foot as well after I had fallen asleep in a strange position. I am on Plaquenil everyday as well as Imuran. I hate the Prednisone and am trying to avoid it but this pain is horrendous. Does anyone think it's something other than the Lupus? It goes away but always comes back. It gets red and hot sometimes as well. I used the analgesic creme and it did help but then my pants stuck to my knee and that was annoying...
