Re: Blood Filled Bump
I don't know what it's called, but it would be best to get it checked out since it does bleed. Anything that can be irritated constantly and easily and has its own blood supply should be checked and removed.
Your son will probably thank you! And it will be biopsied to make sure it's nothing serious.
Best to be on the safe and err on the side of caution.
It's all a matter of perspective!
