<s>[INST] I hit my head really hard this morning on my car door, have a marble sized lump just above my right temple from the hit. Immediately after hitting my head, it knocked me silly and I was dizzy and stumbling to regain balance. I haven t felt right since. Felt sick to my stomach all day, at one point my vision was slow to catch up when I would look from one thing to another, felt like my right ear was under water for a little while. I still don t feel right in the stomach and my chest feels funny. Not sure if the chest thing is from anxiety over not feeling well from hitting my head. Should I seek medical attention or wait it out??? [/INST] You have to consult the general surgeon to rule out brain injury.and lump may be due to hematoma formation. And if needed do CT BRAIN plain to rule out intracranial injury. And other symptoms may be secondary to it.take symptomatic treatment  for it. </s>
