[|Human|] I have a lump on the outer side of my knee that comes and goes. It seems like it appears when I am on my feet for long periods of time or I do a lot of climbing. I did a lot of snow shoveling today and now its back and is somewhat painful. What could be the cause of this?
[|AI|]  Hi, If I were your treating Doctor for this case of a lateral-of-knee lump, I would come up with only one and one possibility that is varicose veins or bursa! Nothing to worry about this and try not to get infected there! I suggest you to go for an FNAC test/USG Doppler of the lump for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
