Contractures
In this, the muscles are unable to relax. There is a depletion of adenosine triphosphate, which is an energy chemical in the cell that prevents muscle fiber relaxation. In this sort of muscle cramp, the nerves remain inactive. When contractures are inherited, they are called McArdle's disease. This is a defect of the breakdown of glycogen to sugar in the muscle cell. If the contracture is acquired, it is called Hyperthyroid myopathy. This is linked with overactive thyroid. Contractures are uncommon. Proper fluid intake, proper calcium and vitamin D intake, supplemental vitamin E and magnesium intake are essential.

I'm not sure what any of that means, but ATP depletion does happen when you exercise and Linda never drinks enough water throughout the day. She hates milk, so a calcium deficiency is possible. Magnesium deficiency happens when you exercise too much. Could the answer be that simple after all these years?
