What Causes Obstructive Sleep Apnea, Numbness In Face, Scalp And Extremities?

Question: I am waking up all night long- Numb face, scalp, extremities, trunk- and not breathing. I previously had Obstructive sleep apnea, but that only manifested while on my back and I now always wear a mouthguard which has solved that issue....This is different; I can be on my side or stomach and still awake numb, cold and not breathing- I have pinched my nose to make sure that I'm not breathing but am not in a panic(As with obstructive) when I wake up- I have to tell myself to breath- again and again....after several deep breaths then the numbness starts to get buzzy and goes away.....At first it happened only a few times a night, but it has now been two weeks since I was able to get a decent nights sleep(4 hrs).....It has gotten so bad now that as I start to get to sleep, I suddenly realize that I'm losing circulation/oxygen, and my breathing has gone down to barely perceptable....I was able to get my doctor(Who's been on vacation) to do a blood test and my Thyroid tests showed low levels....I'm trying to get to see an Endocrinologist....But everything takes weeks, and I can't sleep and am experiencing headaches and now loss of appetite. My pulse has always been low(50-60), temperatute is low(97-98), and blood pressure is low.

Last night I awoke and was numb all over and my arms felt heavy- I tarted hyperventilating and after 10-15 minutes was able to get out of bed...But if I slowed down the breathing, I would start getting numb again, so I went to San Leandro ER....After quite a bit of talk, a very nice Doctor grudgingly allowed me to stay with a monitor on me- I tried to go to sleep, but each time I started to go under, my heart rate would drop below 50 and the alarm in the room would wake me back up. I wanted to get the in-room alarm turned off so I could actually go under and see what would happen, but right then the Doctor came in and stated that my Oxygen level never fell below 97%(I actually noticed when I was awakened by the alarm a couple of times where it was 96% and once below that- maybe 94%) so I was sent home. The big problem here is it' getting progressively worse each night. Everyone seems to want to tell me "Get a CPAP" but if my lungs aren't pumping, that isn't really going to do any good. Now my appetite is off, my movements are non-regular, and I'm cold as heck- 70 degrees in my house, yet I'm layered up with a t-shirt, sweatshirt and heavy flannel shirt. Obviously, I need some tests but I'm quite concerned about tonight, the next night, etc....All this doesn't happen overnight.
