I have a "lump" on my arch about the size of a nickel. The dermatologist said to have it x-rayed by a podiatrist. It looked like a "pilar cyst". I think the common term for it is a "bible wart" It's been there a year or so ... not growing ... not painful ... I'm thinking it one of those things that more pain and trouble to remove, than to leave alone. I'm a 54 year old male in otherwise good health.
Thanks for your thoughts on it.
