I too have T and cramping Cramping is in my feet my toes for some reason but I do red light therapy every morning Just put my foot on a scale it's made by bright health for 28 minutes it's timed and it makes a sound and then you're done No pain it's just like putting your feet on a scale when you're sitting watching TV or at a computer. I think make sure you're eating healthy and you want to cut out sugar as much as possible I did that and it seemed to reverse my peripheral neuropathy from my legs down to now just my feet. Good luck.
