Brian,
A great big welcome to you:

!
Please investigate low dose naltrexone here and on the Internet ASAP. Dr. Pradeep Chopra, one of the CRPS/RSD leading experts, is a strong supporter of this therapy. Please watch his 2 hour You Tube video. You have nothing to lose and everything to gain from the information.
Also there are recommended supplements for RSD. NAC and R alpha lipoic acid. I take these as well as magnesium, rutin, C, malic acid, milk thistle and B12 methylfolate.
DMSO is another beneficial weapon to have in your arsenal, along with Epsom salts and magnesium oil/lotion. DMSO is especially effective for hot CRPS, it is also good for bursitis and other aches and pains. I used a 50% cream, but I have read it is better to dilute the 100% to 75 with glycerin. DMSO is sometimes sold at farm supply stores.
How do you keep the bedclothes off your feet? I used a stool and then later my sister gave me a table thingie that could be wedged between my mattress to hold the sheet, etc off my feet.
Hypnotherapy, biofeedback, meditation, gluten free-paleo diet, yoga-chair, all are recommended. Watch YouTube videos-free intros into these therapies. Look at Tong Ren-very strange. Massage, myofascial release. Acupuncture does not get high marks, it is expensive. I liked it, but the relief it provided only lasted a few hours.
Has anyone told you that you could have muscle knots called trigger points?
Does the VA offer pool therapy? Littlepaw mentioned infared sauna as being helpful, too. Amazon sells a German made infared device fairly cheap. The reviews are excellent. People recommend paraffin wax treatments, too.
I bought two little exercisers that I put in front of my couch to keep my blood flowing and build muscle. One is called InMotion, the other is WonderCore Smart. IMO money well spent.
