my job requires me to stand anywhere from 6 to8 hrs. daily, in a limited area. My calves ache and my legs feel like they have lost strength. It pains me just to sit, rest, sleep, etc. this seems to be constant. mostly in my calves, although the muscles from my right groin to my knee gives me severe sharp pain. takes my breath away, I break out in a cold sweat, once it was so bad I lost control of my bowels. I am looking into air massagers for the legs? I tend to rest my feet and legs at off work time, some how helps yet limits my strength
