Hi and welcome!
Did not know we were on the Dorito bag. I seem to remember some snippet about Evan Ducker being on a bag of Doritos.
Anyway, what you have is probably not technically a hemangioma, since they always go away as a child grows up. I'm not sure what you do have ... you do need to be seen by a specialist. It isn't going to get better with no treatment.
So, where are you located?
One thing I would do is to write to Dr. Levitin via http://birthmark.org/experts.php
and send him a photo of your hand. He might be able to tell you what your next step is.
