I was having a lot of pain in my right knee. I had a lump as hard as bone the size of a golf ball on the side of my knee. Family doctor sent me to see a orthopaedic surgeon. He did multiple test and then the In August I had it removed. He said it was a lipoma and was harmless, he said he got it all! Two months later I noticed the lump starting again. Now pain is back knee buckles on me and will wake me up at night from pain. Surgeon wants to remove it again. Is this going to keep coming back ?
