Hi all, I'm wondering if anybody could give me a heads up about what my boo boo is. It started off as a bump on my shoulder, I thought it was a pimple, tried to pop it, it started bleeding, and kept on bleeding for an entire day. I finally got it to stop bleeding by applying pressure on it for 10 minutes. I have a doctor's appointment on Monday, but would like to know what it might be before I see the doc. Thanks!
