Hi Was In A Crab Accident Back In May Prior

Hi was in a crab accident back in may prior to this I was told I have papidema I hit my head . And now have post concussion syndrome. I had a root canal that went bad and now I have access in my mouth. I have been experiencing confusion. Head pain and throbbing that feels like a bruise or something trying to burst . Its so painful can barely comb my hair but when I check my scalp it looks fine . I went to the emergency room and they gave me amoxicillin. If this is anbrain cyst which I'm hoping it isn't. Will just taking amoxicillin help me . Can I live
