Hi,
I am not sure what is going on with me, I retain my pCO2 , when tested with ABG, also done sleep studies, 3rd one they put me on a bi-pap machine.

I still have vsion problems that come and go, like a blurry vision , confusion feeling,lightheaed, what I call a brain fog type feeling. Needles & pins feelings that started in my feet & toes,burning sensation, also cold, sweaty feeling, now has gone all the way up my legs to groin area. No one seems to be able to tell me what is causing this. I have done some research online, but there is so much out there and can't seem to narrow it down to one thing. I have read about pressure on the optical nerve, also lack of oxygen in the spinal cord, which can cause the numbness , tingling, burning, coldness in my legs and feet.

Anyone have any of these symptoms or suggestions of what it is?

I have a neuro appt next Mon, but this is getting worse by the day and I feel so bad. Also last couple of days chest pain too, but have had my heart tested in hospital and they say all is fine.
