<s>[INST] I had gotten very angry while intoxicated and threw my head very hard against the door. After the fact i had a softball size bump on forehead but with no unconciousness or vomiting just slight headache.It is now 3 days later and the bump has reduced but is still there with the cut marks and scabs still on it also i now have slight nautiousness and some sensitivity to light? What might be wrong? [/INST] Hello, thank you for your question.I've got that you injured yourself in head and developed a swelling after that. If so, you have had that injury over 3 days with no other significant complication, such as vomiting, headache or dizziness etc. Most probably the swelling might be a hematoma that resulted from rupture of some minor vessels in your scalp. As there is no obvious cut, the blood didn't come out but collected in a layer of your scalp. According to my knowledge, cautiousness and sensitivity of light are not concerned with that kind of swelling. Perhaps, these symptoms may be the remnant result of the velocity during your head injury. It may spontaneously resolve with time. And you can put some ice-packs over it gently to accelerate the recovery. It is reassuring and flat to had </s>
