Hi Hubby with RSD--In my personal experience, it took quite a bit longer that just several weeks--actually, come to think of it MONTHS adn MONTHS--and three years later, there are SOME days, depending on "triggers" and flare-ups, that the de-sensitization exercises are NOT very "comfortable"...

After three years w/ RSD, I STILL cannt stand to wear "tightish" sleeves on my arms (WINTER)--summer NO sleeves--so I just find men's jackets and shirts that are EXTRA large, baggy, (like super-soft flannel, the BIGGEST size I can find) and I also look at how the arm seams are constructed--if they are wide, raggedy seams with scratchy thread (especially that nylon stuff that is like fishing line)...it goes right back on the rack!!!

I don't know what size your hubby is, but maybe going to a store for the "larger men", where they have the extra-extra big sizes might help him find something a lot looser on the arms and more comfortable in the winter.

I hope he finds something that is warm and COMFORTABLE!
