Several months ago, I hit my head hard. I did not lose consciousness but I saw black, vomited and had dizziness for hours. My head literally took out the freezer door drawer (that was full of frozen goods)! I didn t go to the doctor at the time. Even after all this time, there is still a little bump on the top of my skull. Since then, I will have this intermittent, sharp pain in that spot. Will lasts a few minutes and go away. However, today my head feels like it is going to explode out of that spot. Hurts really bad, does not feel like my typical migraine, and is accompanied by nausea and dizziness. I have tried some migraine medicine but it is not working. I have been stressed lately so it could be a tension headache. But could it be something else, even months after I hit my head??
