I am having problems with my scar. I am 11 wks out and for the last week or more it has become redder or more purple (in am). It had been looking better. It also feels very tight when I walk. The tight band is better after my MUA Jan. 18 but now the tightness seems to be in the scar. I have been manipulating it as my PT showed me too, to keep it from forming scar tissue under, plus she manipulates it when I am there. It is also more sensitive to clothes and bedding when I sleep. I also am waking up in the night with painful aching in my lateral thigh and down the leg. I have been very fortunate up to now with not having sleep issues. Saw my OS yesterday and he has diagnosed me with CRPS (Chronic Regional Pain Syndrome). When I read about that it says it is rare and often over diagnosed. Anyone been diagnosed with this after TKR or had problems with their scar this late out?. He is sending me to a pain management clinic to receive injections in my back to help. I don't know what to make of this? Josephine, have you heard of this after TKR. I am just not sure he just doesn't know what to do with me, lol. But on the other hand since he doesn't like to prescribe pain meds maybe I can get something finally! Also Josephine when you have an MUA does it set you back and by how much? I am not sure if I should consider myself 11 wks out or go from the MUA which would make me about 6-7 wks? Thanks for any light you can shed. I look up scar but I just don't see anything about someone having issues with it like I am having.
