My problem seems neurological and started about 10 months ago and since then i have had a constant very slight pain on left side of my head. it is very hard to describe it. it feels kind of like a numbness in my head and it feels like its on the surface. it gets amplified when i get annoyed or angry or also when i try to remember something and i cant and also other circumstances. I also have a habit of moving my jaw alot. I understand my description of this problem is very obscure but i was wondering if anyone could help me with this.
