In addition to stretching, hydration, Potassium, and Magnesium, and setting an alarm to get up in the night for more stretching, this "creation" has helped me in reducing both the severity and the frequency of night time leg cramps that always occur for me in my calf down to my ankle or foot. Never above the knee.

I got a regular sock of mine and a piece of fleece (could be any fabric) 3 inches wide and 64 inches long (I'm 5' 5"). I wrapped the end of the fleece around where the ball of my foot is on sock 2x and sewed it on. Not so tight as to restrict my foot movement within the sock. Did not want to make the tube of the sock tighter.

That left nearly 5 feet of "tail." I made sure I aligned the tail so it streamed off the bottom of the sock, then came over my toes on the top of the the middle of the sock. I sewed all that on the sock to anchor it. Again, I did not want to make it too tight. The sewing on the top of the sock stops about half way between my toes and ankle, leaving the tail free.

When I have the start of a cramp in the night, I pull the tail toward me so my toes are pulled toward me. This flexing of my toes, stretching my calf helps alleviate the cramp.

So that the tail is always within reach of my hand, I run it up my leg and through my underpants and out the top of my pj bottoms. The top of the tail then hangs near my hand, within easy reach. Since I get cramps only on one side from past injuries, I only have one of these "creations" but you could have two.

Since I made this in June, just wearing it has somehow reduced my night cramps to 2 times in 6 months instead of once every 10 nights. I don't know how it could be preventive other than something psychological or that my right foot feels a little different inside this "creation" and that sensation has some effect on the nerves. Who knows? But the 2 times I've gotten cramps in the night, I just pulled on the tail, which flexed my foot and the cramp did not last long. In the past the cramps could come in waves for 20-30 minutes. Sometimes I'd be screaming. Also, the two times after pulling on the tail, I was not hobbled for the next several days after the cramp, which used to happen a lot, probably because the cramps used to become much more severe without the quick intervention.

RE: Theraworx--I tried it for about 2 weeks and got cramps. Maybe it takes longer?
