Hello and welcome. I'm Dr Chip
This is most likely a type of tension headache from spasm of your neck muscles but it may also be a sign of a disk problem in your neck so you need this to be evaluated and to get an MRI scan of yur cervical spine.
About 95% of all headaches are painful but not dangerous but you need to have this evaluated with an exam and the MRI if the doctor thinks that's warranted.
Please let me know if you need any more information and please remember to rate my service to you.
