"Support Stockings Do They Really Work"

My wife has Reuhmitiod arthritis and had bad flare ups in her ankles as they swelled up very bad a lot on my wife when she worked on her feet 12 hours or more a day. So my wife tried support stockings and wow they seem to help her tired swelled feet a lot as her feet look like 25 years young again. My wife gives support stockings a true big ten.
