Hi everyone I am new here I had my knee replaced last May and am ten from my surgery .I was doing good for first two months finished physio then and had my range of motion of 120.then in Julythen the kne suddenly swelled up So since then after feeling like it was gout just by the way it was rea ting and cherries gave me relief I had had blood work which shows my urate is up I. My blood so my family dr put me on gout meds having foible take one of them but the three day one allowed me to bend more then the 90 degree range I now have.So my question is how do I hanle the pain I am still in and are there any other things I can do to try to get my range of motion back to the 120 I need to get to.
