For 23 years I have not been able to sit for more than 2 minutes and when I sleep at night I get terrible muscle leg cramps attack at night from 1 to 10 per month. The 3 lower disc in low back are badly degenerated. I discovered 3 weeks ago if I take a cold shower between 11:00 to 4:00 during the day I eliminated the terrible leg muscle cramps at night. The sitting problem is not resolved; however, the ligaments in the lower back do improve after the cold shower. I have tried ice pack therapy but does not work like ice cold shower therapy to eliminate leg cramps at night.
