question: My pinky toe has a swollen lump on the top of the knuckle. Its not on the bottom of my foot the top only. I am concerned because I am on my feet all day. The right foot is the culprate, I noticed it about 2 weks ago. Any idea wha it might be?. I am a male of 26 years of age ad not over weight. I am adopted so i do not know what could be hereditary. Please help.
