|Diabetics and others with circulation problems have special issues that need to be taken into consideration in order to keep feet healthy.|
The reason Epsom salt can make a problem worse is because magnesium sulfate is overly drying for the already dry skin that often accompanies a diabetic condition.
Instead, you are safer to just wash your feet with unscented soap and lukewarm water before drying and following up with moisturizing lotion all over the feet with the exception of lubricating between the toes.
Diabetics are often low on magnesium, which could help with sugar and cholesterol levels. Nonetheless, before you start self-treating with a magnesium supplement or mixing with your medications, please seek the advice of your physician.
