I about a week ago I hit my head pretty hard in the four head area I went to the ER about 12 hours later due to Head pain. They did a CT scan and told me everything was OK. After that my symptoms stay the same and I ended up going to the ER again two times each time they told me I was OK. Now, a week later I'm still having had pain in the back of my head today it's worse than it was yesterday and I don't know if I should go to the ER again or if there something wrong my symptoms have stayed the same except for the head pain today what should I do?
