Don't know if it would help you or not, but I was given specific neck stretches by my PT, and told that I would have to do them for life. If you feel your head symptoms and neck symptoms are related, you are not alone! While I haven't been able to put my finger on exactly what my recurrence trigger is, I certainly notice my neck is worse when my head is worse, and vice-versa.

I also started deep tissue massage this year, focusing on the most painful part of my neck. I say massage...it started out more akin to torture sessions, my neck was so tight. While it hasn't completely "cured" my head (or neck) issues, I feel that I've continued to make progress.

I suspect everyone is different in what helps and hinders just a bit, so as long as what you are doing doesn't make it worse for you, why not explore it?
