Answer
K,

You likely strained (or sprained) the top of your neck and you are experiencing cervicogenic headaches.  Cervicogenic literally meands that the cervical spine is the generator of your pain.  I would suggest seeing a chiropractor and getting some soft tissue therapy and joint manipulation.   Likely you will find some relief after your first visit.
