I had forgotten to mention:
I am having great luck with magnesium chloride spray.
I have found this to be more powerful than the Epsom Lotion, which is magnesium sulfate.
The lotion is less messy.
However, the spray is so much more helpful to me.
I am using
Life-Flo Pure Magnesium Oil (Spray).
This is 100% pure.
Approx. 66 mg. elemental magnesium for every 4 sprays or 560 mg. per teaspoon.
I could not sleep through the night, despite all of the meds and topical solutions, until I had started to use this magnesium chloride spray.
I massage my lower legs and feet with this form of magnesium at least twice a day. I make sure the night massage is just before bedtime. This quiets some of the deep burning pain and stops the severe cramping/spasms in feet/toes/calves.
If you have any open lesions or cuts on your skin, this formula may sting, as it is a "brine."
This spray/oil is making sleep possible for me right now. In addition to the pain/spasms relief, this feels very calming overall.
Hope this helps someone.

P.S. Life-Flow offers many different magnesium chloride products, including the spray/oil, lotion, gel, sports formulas, etc.
