My boyfriend and I were running through the snow, and he slammed his head against a concrete wall. There's a long gash across his head right at his hairline, about two inches in length, and less than a centimeter deep. This happened about an hour ago, and the bleeding is already slowing down and clotting. And there are no signs that he has a concussion or any other serious symptoms such as nausea, vomiting or surprisingly, a headache.
We don't want to go to the hospital and I've been treating him with peroxide in the meantime. What should I do now? It is large enough to get stitched, but if it's already clotting there's really no point, especially if it's taken care of.
What else should I be looking for and doing?
