question: Good evening.  I have been feeling light headed on and off every day for the past couple of weeks and lately it seems to be getting worse.  Today it was sliglhtly affecting my balance.  I feel a lot of pressure, 8-9/10, in the front, left side, and mid back of my head.  When I change positions of my head, the lightheaded sensation is worse.  My BP is 140s/90s, HR 70s.  Tylenol and Ibuprofen helped a little bringing it down to 6-7/10, but I still feel aweful.  Something doesn't feel right and I'm worried, but don't know if I need to go to the ER or not. I have already seen my PMD and don't know if I need to see a neurologist instead.
