[|Human|] I just discovered a soft spongy lump on my elbow - It does not hurt, can be moved around, and was not caused by any injury that I know of. It feels strange and is about the size of a quarter. Should I be concerned - will it grow in size or become painful? It is actually on the bone of the elbow itself.
