Yes I too could never tolerate cold or even heat or anything on my rsd area. I was told that the blocks can help with swelling though for me I seemed to feel and look more swollen so I have no clue. Also other treatments like the scs or meds.For me I have different sized tennis shoes for the day to accomidate my growth in feet. I also am very slender but wear plus size women socks. I hope your wife feels better
