Hi while brushing my teeth today I found a small red dot and then while searching the net it sounds like a blood blister and I popped it. When I did that a tiny dot of blood came out. What does this mean? I mean how did I get it over night? Is it something I should be worried about? I have 2-3 ciggerettes a day does that have anything to do with it? Please Help

Nothing to worry about. Sometimes they just happen.

You could have bit your cheek or even hit your cheek with a toothbrush. They will fix on their own. The place you worry about is the eye.
