I suffered from leg, foot, toe, shin cramps almost nightly. The shin cramps were the worst. I tried potassium and magnesium supplements with little relief. I know this is almost too simple to believe but I started eating a half a banana each morning. Shin cramps are totally gone, I still get the occasional calf or toe cramp but those are rare and maybe I just need to eat the whole banana. When I think of how many years my sleep has been disrupted with these excruciating muscle spasms, I get annoyed with myself for turning to supplements rather than food to supply the needed nutrient. I hope this works as well for others as it did for me.

Oh, I even had a L4/L5 spinal steroid injection to get rid of these cramps. Did nothing.

I think the docs don't understand issues of nutrition -- they are more focused on medical treatments to solve issues.
