Have any of you tried an IF stim for your RSD pain?
(inferential stimulation) - it is much like a TENS unit, but is more for muscle stimulation/healing and pain relief.
If you have spasming muscles, cramps, etc, that are an issue , an IF stim might be more helpful than the pain blocking from a TENS.

Basically it has different frequencies so the unit can be turned up higher with no zapping, and it goes deeper into the tissue.

Many chiropractors and PT places usually have them to see it they would work at all for you or not.

I had an annoying pinching/catching in my low back for a week and then remembered my IF stim, 1 hour and that pinching is gone.
I'll do a few more sessions with it to make sure it stays away..
