DS, who's 2, developed what I thought was a blood blister on his neck about 6 weeks ago. He scratched it a few days ago and it bled loads. The GP has examined it and said it was a hemangioma. He asked me several times if I was sure it hadn't been there since birth - it hasn't.
He said they generally don't remove them. Advised us to cover it up with a plaster if his clothes aren't covering it, and that if it bleeds for more than a few mins to go to the docs, or the hospital if the docs are closed.
He said that it wasn't sinister, but needing to react that quickly has alarmed me a little! Also I'm now thinking, should I have a plaster on it all the time in case he scratches it at night and bleeds without us realising?
Looking it up on the internet, it seems strange that it's developed this late too but it definitely wasn't there a few months ago.
