And lay on lots of ICE !! I couldn't get out of bed the first 2 days, but it gets better each day.
And yes it sure is wierd how certain movements will send an unexpected 'surge' down the spine!
Even blowing my nose sparked a buzz!
My rep actually used the term "looking down is your 'off' button"..... ? meaning when your neck stretches downward, it causes the tingling to practically stop and can be used as an 'emergency' measure, should your controller spike the sensation too high.
Alot of it is a trial and error thing. I still don't quite understand how my dang handheld controller works! I get better results just doing wierd maneuvers with my body! ha.

As far as the incision pain.....just keep reminding yourself of all the years of constant pain you've been dealing with. This part is just temporary.
Best Wishes and keep us posted!
