Not long after I was diagnosed with PPMS, my right leg started spasming at night. It only happens when I am trying to sleep or am sleeping. My right leg doesn't do much all day except for being dragged around all day by my left leg. I asked my Neuro about why this would be happening and got the "we don't know" and another prescription.
I am thinking that it has to do with dainage differences when I'm laying down. Possible Azygous stenosis? I am scheduled for treatment on the 13th of Sept. This is one symptom I hope to lose. So does my wife.

Any thoughts?
