I agree.... there is lots of bad data. Because my problem I higher up in the lumbar it did not effect feet. Mine ran through thighs down to inside of knees. Also hips, and on occasion intestinal issues. I also had about a week of pain in the groin region. Yeah, that was not fun. In my case, because of bad muscle atrophy, it kinda became something that had to be done and not so much an elective. I elected not to for a few years.... thanks for the well wishes!
You situation and that of others with other than pain issues is much different that “just” the pain. In those other than pain issues the relief required becomes other than elective.
My wife is shaman of sorts (kidding, a little) and read that tonic water relaxes muscles. I began with a small can of the diet variety each evening and it allows me to sit in a chair and read without wiggling for hours. Seems to help with sleep as well. Not a drinker but I may mix it with a little gin and lemon after I finally go to town again to get some.
