hi im new here hubby has rsd 3 yrs now and has that same problem people wanting to pat you on the arm or back he has rsd right hand now traveling up right arm, im happy to found this site for him and me. i bought my husband a nice sling it come up higher on his arm then the ones from the drugs stores and nice padding on it seems to help with warmth as well , and his arm can relax instead of always trying to keep it in a bent postion becasue he cant let it hang straight down. you all are great here.
