I am now 4 mos following total knee replacement and in the last few weeks it hurts more, swollen at the knee cap and on sides and below and warm. I had been doing great but did too much for a week, walked on uneven sand a lot and since then it has set me back, I can't bend as much as I could, the swelling worse in evening runs the horizontal line of my scar, rather bumpy along the stitches it appears, below, above and on the inside of my knee. I have gone back to surgeon a couple of weeks ago when I had a fever which went away the next day, but they said due to the uneven ground it flared up. It's not red, I had the fever only a day and evening and that was over 2 weeks ago. Since it continues to be painful I am concerned, I don't want to be a pest to the docs who seemed to think it is normal but wish to get my movement back and pain gone.
