October 21st 2017 I was hit in the back of the head several times. The rest of that week I had mild headaches, but 800mg Ibuprofen took care of them. I still went to school and work. I felt like I was getting better. From October until March just occasional headaches...

Then end of March 2018 I started getting terrible headaches and neck pain. It feel likes pressure in my head and it feels like blood is rushing to my head. I can't bend down or get up to quickly. Since March, I have been in bed almost everyday with terrible head and neck pain.

Does anybody know why I was OK (for the most part) from Oct-March and then all of a sudden in March it got really bad?
