My RSD started in my foot and has worked it's way around my body.
When I first began physical therapy, my therapist begged me to keep wearing the same kind of socks, jeans.....basically to not change my clothing type. She said it would help to desensitize the affected area.
Oh how I have cursed her over the years as RSD has spread from toe to head.... but I thank her too... It still hurts A LOT!!!! BUT, I still wear the same name brand of clothes as I was 9+ yrs ago. My normal dress is jeans t-shirt or polo.....all cotton. If by chance I have to wear something different, I will go into a flair.
I hope you find something that works for you!
<----- gentle hug.
