I Ended Up In The ER Last Week With A

I ended up in the ER last week with a severe spike in blood pressure. They said nothing was wrong except my HCT and HGB levels were a little high. I have dizziness and blurred vision, as well as, hearing issues for the last 3-4 weeks. Also extremely tired... to the point I am dozing off at stop lights. I went to the physician on Thursday of last week and she said she thought it was my thyroid so I had a blood test today. My thyroid level is normal (1.27) according to the hospital; chart. What else could be causing all these problems? Doctors are saying I am ok but my body is telling me otherwise...
