i too use the columbia shirt. i use it as an under shirt. though I don't have the beast in both arms and it isn't as bad in my arms as my legs but i find it helpful re warmth and a more comfortable way to control the swelling in my arm. my legs I'm stuck with compression stockings and i use them as only if i can't avoid it. i already use sneakers that are 3 sizes larger than my shoe size . but when I don't fit into them or my regular socks i need the compression stockings. and boy when i get home I can't get these things off my feet quick enough, and nothing seems to warm my feet and legs up, unless RSD decides its time to burn instead of freeze. owe!!!!
