@lweave2 @erikas @sunshininsunshining dEven if you are taking oral magnesium, when those cramps and stiffness hit, you need to apply magnesium directly to the painful area. I suggest Dr. Shealy's Biogenics Magnesium Lotion. I've always purchased it at health food stores, but it is now available online. Amazon price is way too high, so Google search for other sources.
