I'm new too. My pain came first in a grocery store. I figured my shoe laces were too tight. A couple of years later it became a real problem with pain in my ankles and feet. Cramps were terrible. BUT, only two things happened before the pain. 1) Grocery shopping for longer than a 1/2 hour. My new shoes helped. 2) Alcohol. I sat down for a small glass of wine and that nite in bed I thought I was going to die from the pain in my ankles. I am not diabetic, but apparently pre-diabetic. Had to give the wine away.
What helps. I take magnesium capsule before going to the grocery store. I also take a capsule in the morning and again at bedtime. I take potassium in the morning, too. It definitely helps me.
