A clogged artery ... oh no... meds, but no stent?
(What a mystery - you elude diagnosis! How frustrating that is. It took me 20 years of malpractice and miserable, expensive "treatments" before the gluten diagnosis, which improved my life more than any doctor did).
Arteries. You somehow escaped surgery? These things are routinely "fixed" with "Roto Router" - my mom's carotid is half blocked, and they want to ream it out. She had a spell of dizziness with weak arms and legs. At her age (85) one has to go the medical "profession" to see what's causing such symptoms (hers lasted two days, then went away.)

My father-in-law suffered a nicked trachea when his carotid was cleaned out. For an entire year he couldn't swallow and fed himself at home with an IV machine. Awful, awful. He ate very little, and very slowly, then died a couple years after that invasive surgery (and he didn't sue the surgeon who nicked his trachea).

Maybe my mom will stick with meds, not Roto Rooter surgeons. Monday, it will be two weeks without test results. Small towns can be terrible places for medical "care." My sister's cancer (and a blood clot as well) were misdiagnosed/overlooked/dismissed in this same town.

The world is filled with brilliant, hard working doctors who save lives and work miracles.
I just haven't met any of 'em myself.

May this continue to work: "I move my head when I first feel it coming on and have not fallen since I started doing this."

I've learned to turn my whole body instead of turning my head (to avoid triggering vertigo).

Little things....
