About a month ago I went back on my CPAP (continuous positive air pressure for my sleep apnea).

(hate/hate relationship) The dark circles under my eyes have improved; however, now I have a new problem.
Since my MS dx one year ago the constant numbness has been contained in my left arm and some in my face; however, it has recently "leaked" over to my right fingers and gradually up the arm.
Occasionally while seated in my computer chair I put my arms up and lock my fingers behind my head. In about a minute my right bicep starts to visibly jump around. The spasm goes away as soon as I stop the slight forward pressure on my neck, where my marble-sized lesion is.
So, I wonder if the CPAP strap is having the same effect on my neck: is that why the numbness has spread? Is it a plausible theory or not?
Now I don't know if I should sleep with the thing or not.
