Hi again, revbobmat, and thanks for your post. You may be aware we cannot provide medical advice or diagnostics over the internet (for your own safety), but your concern certainly warrants a reply!
You may be interested to know there are various medical conditions that may cause a level of 'syncope', or dizziness. As well, an unsteady gait, loss of balance as well as other symptoms may be included. It is also possible the pulmonologist and/or general practitioner may not be familiar with these conditions.
My suggestion would be to seek out the advice of a good neurologist. I will share I was experiencing something similar and, after a battery of diagnostic tests, all which turned out to be negative, it was determined that I was mildly dehydrated. When I investigated further, it turned out I was NOT drinking a sufficient amount of water during my day. It was subtle, but it was there. It took a fairly well known neurologist (and his PA), to diagnose this even though I had been followed by several other high level physicians concurrently!!
I share this not so you'll think you're having the same condition but, more importantly, so that you will consider seeking out a physician who can properly assess your condition.
What do you think?
