I have been experiencing dizziness issues for almost 2 months now, on and off at first but now all the time when moving around. Took some antibiotics (azythromycin) for a sinus infection (from a walk-in clinic) and it helped for a few days but then came back even staying on the antibiotics. Went to the ER because I was very concerned and couldn't wait to see my regular doc, they did CT scans of my whole body and found nothing wrong, sent me to a cardiologist. Blood pressure and heart monitors for 2 days, came back normal (BP ranged from 120 to 142). Also found out that I have Mitral Valve Prolapse, but a mild case and said it's nothing that would cause dizziness. Blood work showed high level of calcium and low level of phosphorus. They seem concerned about the calcium being high in my blood and low in urine samples but don't think it's causing dizziness.

First noticed the dizziness walking around a mall, thought I was going to collapse or faint. Also noticed it a couple times right after eating. Airplane takeoff made me feel like I was going to faint, as well as going up in an elevator. Finally got to see my regular doc and they said my eustachian tube was probably blocked and told me to take regular Claritin and Flonase for 2 weeks. It has been over 2 weeks and I'm still experiencing the dizziness, although not as bad, but still notice it when moving around, not when I'm sitting still.

The regular doc doesn't seem to know and I've asked to be referred to an ENT. I think an inner ear problem would make sense with alot of the symptoms (airplane), but what about feeling dizzier when going into a large store or mall? Is this because of air pressure difference? Going back outside the store helps me feel better. What about the dizziness and somewhat a shortness of breath right after eating? Why would I feel it worse right after eating a meal? Also have noticed strange pain in my neck and back once in a while but not all the time so I'm not sure if that's related but thought I'd mention it. Please help.
