Hi, I'm 82 years old and in pretty good health. I jog a little over a mile every day. My left knee began giving me a little discomfort on and off for the past couple of years. About three or four months ago I noticed a lump developing on the out side of the knee. It would go away for a few days then return. The lum is sort of hard, about the diameter of a half dollar, and sticks out about a half inch at most. It doesn't hurt at all if I attempt to compress it. It's amazingly almost completely goes away (where could it go?)!!! It seems to be more permanent the last couple of days (not completely going awayas it had been). The last couple of nights I've been awakened by pain in the knee. If I change the position of the leg the pain will most often go away. I'm scheduled to see my GP for an annual physical exam in about six weeks. I'm not at the point of discomfort where I need to take anything for the pain, but I'm getting to that point.
What do you advise?
