Hi. Is this new? We do have the bursa at our knee cap and we can have bursitis. The bigger moving lump may be your bursa. It WILL move. Does it hurt to kneel on your knee for more than a moment? You could have a cyst, a tumor (don't panic, often benign), gout. These all could also cause lumps in that area. https://www.healthgrades.com/right-care/bones-joints-and-muscles/knee-lump I think that if it isn't causing you any discomfort, I'd schedule a physical for sometime in the future and mention it then. We all should get physicals annually so that's a good time to talk about this. If it is painful or starts to cause more issues, then schedule an appointment sooner. I would think to start off, your primary care doctor can direct you if you need further evaluation for an orthopod.
