Hey Pete,

I've had RSD for 25+ years.
And, massage is rarely indicated, except for one kind that I'm aware of.
Alexander Technique. It really worked well! (Have you heard of that?)
It's very soft and gentle, and concentrates on "extricating any pent up energies from the spine, on out, through the extremities. (It has admittedly been a long time since I've had it done). So, feel free to add to or update my memory!

Soft Tai Chi kind of stuff.

(a "Vigorous Rub Down" kind of massage, is the worst, it can start all the bad pain to flare, so, be careful).

Migraine responds really well to a neck massage and a soft chiropractic adjustment, imho.

Good Luck to ya,

Pete
