I have a lump on the outer of my left knee. My GP says it's the jelly stuff that surrounds the joint that has come away I had an x-ray which didn't show anything. I don't want to keep taking pills my GP says that nothing can be done. Its very painfull when I have walked for a while or driven. When I first mentioned it to him he said it was either a steroid injection or op but now its nothing can be done HELP.:confused:
