18 days after butte implants, my legs and mostly my knees are swollen past normal appearance. They feel tight and painful. I have done everything the doctor has said and yet I am retaining so much fluid. I only weigh 105 pounds, yet I look like I weigh 150 ponds in my legs and knees. My butt looks great but still is swoolen. I had fluid drained off of one side of buttocks 3 days ago and it feels better, but legs and knees are aweful. I have put support socks from the actual surgery back on, am not sure if this is the thing to do? Can you help?
