I found massages very helpful. If you can get a cranial sacral by your RMT those helped with some of the tension for me quite a bit. Some massage therapists can do a bit of Osteo, that was helpful too.

I recently went to see a doctor of Osteopathy (D.O) which was able to fix some of the issues of my neck and back that massage and chiro was unable to resolve. Many of the odd sensations in my head disappeared completely and my jaw which was cracking and was very tight is now much better.

Good luck
