Hello. On my left ankle, around a year ago, maybe a year and a half, i got a small, movable, painless lump about the size of a pea on my left ankle. over time, it had grown, it is now about 1" by 1.2", still i feel no pain, although now i can actually feel it, and it has come to my attention that it bleeds when i attempt to buff it down. I have purchased various compoundW products but i would like to have a more thorough understanding of this lump before taking any further actions.. Should I make a trip to the hospital or just freeze it off? (I've a history of cancer in my family, and absolutely no trauma to my ankle in the last two years. )
