How is the palm always sweating and cramping?

It may be related to calcium deficiency, fatigue and catching cold. Suggest taking a break. Appropriate calcium supplementation. I suggest taking Goeltsch D orally. Eat more bone soup, crucian carp soup and lean meat. Drinking more milk is the safest and most effective way to supplement calcium. The content of calcium in milk is very rich, which can reach 100 ~110 mg per100 g of milk, and this kind of calcium is natural milk calcium, which is easily digested and absorbed by human body. Besides, medicine tonic is not as good as food tonic. In addition, if severe sweating leads to sodium deficiency, it may also lead to this symptom. The suggestion is to drink a little light salt water. You also need to pay attention to prevent colds. Keep warm, and use a hot water bottle with a hand warmer at night. Pay attention to these things, and they can generally be improved.
