I had a follow-up appointment with my ear, nose and throat doctor today to see how I've been doing. Although I haven't had any major bouts of vertigo since you put me on the diuretic I still have moments where my equilibrium is off.  Today, I also saw the audiologist who check out my ears and ran some test.  The cool (and gross) part was that when he was checking my ears, I could see what he was looking at on a monitor in front of me.  To see those clumps of ear wax and the hairs was nasty.  But he said everything looked good.  I also passed my hearing test with flying colors. So what is causing all of this?  The doctor thinks that my eustachian tube may be inflamed and causing fluids to be backed up so he prescribed some steroids in hopes of reducing or eliminating the inflamation.  Guess I'll see what happens when I start the medication.
