I have a lump that is semi hard, the size of about 3/4 of a golf ball on my foot right below the bone on the outer or distal side of my foot. It is big and I just noticed it a night or so ago, then I noticed one a little smaller but same consistancy on the top of other foot right below the ankle, . Both feet? smae kind of thing? Should I be worried, I can almost feel a vein or two inside the big lump, not water retention in feet as I have been very familiar with that in past. Elevated it, ised it, and it is not decreasing in size either one of them. What is this, should I worry?
