Ive got Fibromyalgia/CFS and benign fasiculation in both legs. I run around busy Emergency Assessment /departments for 8 hours and my legs don't ache at all ( when i stand in teh kitchen at home without my CS 's on I manage an hour or so before i ache.) I have started to wear CS's at home and out and about now - they allow me to do so much more and get on with life ! Thank you ! Don't ever stop selling these !
