when i try to relax the muscles in my neck (posterior part near cervical spine) I get this pain to the right of my cervical spine (C1-C3) Its a shooting pain and when i feel it I tense up the muscles in my neck to avoid this pain.
This also happens when i rest my head on certain chairs headrests.

could this be a clot? this doesnt happen all the time, maybe once a week or so.

i also lost my glasses recently and have been squining a lot more.

any ideas?
