I found some OTC leg cramp med, plus I take a potassium tablet when it happens, seems to make it subside fairly quickly. Hubs insists the pills don't work, but then he hates to swallow pills. I make him take the pills anyway, then rub the top of his foot until the tendon relaxes. I just wondered if anyone else got this. I asked my mom, she says she's never heard of anything like this.
