Dizziness/lightheadedness And Sinus Pressure

In early may through late june I had occasional dizzy spells. I would feel lightheaded and woozy for hours and experience occasional moments where I felt like I would pass out. There was some nausea and my eyes hurt when exposed to light. There was no headache or pain. At the same time I had extreme fatigue, was unable to do even basic things like grocery shop because of lightheadedness and fatigue.

I had no doctor at the time. At the end of june a particularly bad episode of feeling like I was going to pass out caused me to go to the emergency room. They did blood work, a cat scan, and x-rays, and everything was normal. I was on metoprolol for high blood pressure at the time yet my bp was high (185/95) so the er doc determined my bp caused the dizziness.

The next week I went to a new gp doctor who prescribed lisinopril to replace the metoprolol for my blood pressure. I had more blood tests and am not pregnant, anemic, dehydrated, diabetic, nor do I have heart or circulation problems. With lisinopril my bp has been normal now. The fatigue/dizziness seemed to improve on its own by early july. I had only a few brief episodes of a few minutes duration through the rest of july and august.

However, the dizziness and fatigue returned earlier this week. Since tuesday I have been experiencing the same symptoms as before. I'm noticing severe sinus pressure this time, though, in my cheekbones, teeth, and between the eyes. No headache but the pressure causes a certain amount of pain.

I presume my sinuses are the problem. Tuesday I switched from nasonex to generic flonase.

What I would like is some relief from the pressure and dizziness. I've taken claritin and the generic flonase, 4-way saline moisturizing nasal spray, and tylenol, but to no effect. Any suggestions would be greatly appreciated. I can hardly do anything, as even watching tv or reading causes nausea and dizzy spells when I feel this way.
