Been to the ER with numbness in arms, pain and numbness in neck and back, headaches dizziness, etc. They sent me home with bupap. Wat should I do?

Followup with Ur doc. They evidently did not find a serious health issue that requires hospital care (like a heart attack). If you have sleep apnea or other reason for such therapy you should followup with your regular doc to manage any other health needs.
It's a conundrum! You have many symptoms which don't fit any specific disease pattern that we know of! having said that, i'm certain these symptoms are distressing to you! since nearly all your symptoms are neurological, i believe your best bet is to make an appointment with a local neurologist. Good luck!
