> How on earth do people get this level of nerve testing.

Be diagnosed with MS, have really good medical coverage, and live near a highly respected MS expert.

Anyone know if sleep deprivation from sleep apnea causes global, temporary loss of sensation or (permanent) neuropathy?

I lost a large fraction of sensation everywhere. I'm tired af, don't sleep very well or very long, and feel like s#!7.

(Been tested for lupus like 10x.)

Sleep apnea causes a lot of exhaustion and stress. Really hard on body. Getting a cpap was a massive improvement for to my life.

10 years later I was still declining hard. Got diagnosed with Sjogrens, a cousin to lupus.

Ouch. That's no good but glad they narrowed it down. I've always had read areas under my eyes and dry eyes, and now dry skin on my forehead and around my mouth.

Back to OSA: I have tachycardia and hypertension controlled by a beta blocker (propranolol er). Also, depression, ADHD, and (physiological) anxiety. Can't and could never run a mile to save my life. Haha. Could/can do explosive intensity exercises but never anything more than very low intensity like walking or bicycling.

I wondering if I have pulmonary and/or circulation issues on top/because of OSA that limit moderate aerobic exercise capacity. (Heart is unremarkable per 12-lead ECG, stress echo, and catheterization at Stanford Cardiology a few years ago.. actually performs very efficiently under load.)
