Bony lump on patella
On my right knee on the patella specifically, I have a hard bump. It is not movable. It is very hard, and seems to be on the actual bone. If I ever hit it the pain is horrible. It bruises easily as well. I can see the lump when the knee is bent and when it is extended. It seems to be right in the middle of the knee cap closest to my thigh superficially. The other knee does not have this, and it has been present for over a year now with no real change. If the knee is bent for a prolonged time, I feel strain in the area where the bump is present. Also, while bending down and up, my knee (s) crackle horribly, and pain is felt right where the bump is.
