Does anyone else have this. Let's say your writing and the muscles in your hand just lock up to the point where you have to move it with your other hand and that can happen anywhere in your body. For me hands and arms.
Muscle cramps are usually harmless, but they can be caused by some medical conditions. Narrowing of the blood vessels leading to the legs can cause muscle cramps that go away soon after exercise. Nerve compression in the lower spine usually caused by herniated discs can cause cramp-like pain the legs that gets worse during walking. Low levels of potassium, calcium and magnesium can also cause muscle cramps. www.mayoclinic.org/diseases-conditions/muscle-cramp/symptoms-causes/syc-20350820
