Hello my left eye is getting a muscle contraction feeling quite often. This is the latest syptom. First it was a strange tight pain at top left of skull, occasional short lasting numb feeling in left side of face and then a pop feeling in top of head and immediately after my mouth filling with about a teaspoon of blood that comes between two molars on the left side bleeding stops immediately but comes back here and there if I suck between those teeth to draw it out. Dentist can t see anything to have caused that. Left arm is pretty much always feeling strange and uncomfortable.
