My problem seems neurological and started about 10 months ago and since then i have had a constant very slight and dull pain on left side of my head. it is quite difficult to describe it. it feels kind of like a numbnessin my left side of 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 things and i cant which makes me angry. I also have a habit of moving my jaw alot in different directions for no reason or sometimes i try to spell words by moving my jaw(stuoid). I understand my description of this problem is very obscure but i was wondering if anyone could help me with this. I have seen my GP but he didnt know what the problem was. I am a 24 year old male living in london. I get stressed very frequently. I also have other conditions such as acid reflux and chondromalacia patellae for which i am starting physiotherapy vwery soon.
