Why Do My Hands Experience Muscle Cramps?

Muscle cramps are actually a normal physiological condition. Generally, we may encounter thigh cramps, which do not require any treatment, and the discomfort caused by cramps will ease over time. Cramps in the hands are also very common, mainly due to long-term calcium deficiency in the body or long-term nerve compression, resulting in a nervous tic symptom. There are also many ways to relieve hand cramps. Muscle spasms (commonly known as cramps) are involuntary tonic contractions of the muscles. Muscle spasms in the calves and toes are the most common, and the pain can be unbearable during an attack, lasting from a few seconds to tens of seconds. Especially when cramps occur in the middle of the night, they often wake people up. Frequent leg cramps are mostly caused by calcium deficiency, cold exposure, or compression of local nerves and blood vessels. In daily life, one can appropriately supplement calcium, expose oneself to the sun, avoid compressing the nerves and blood vessels when sitting or sleeping, apply heat and massage to the local muscles to enhance blood circulation. If there is no improvement, one should seek medical attention. 1. Systemic causes such as high fever, epilepsy, tetanus, rabies, and calcium deficiency can all cause cramps. 2. Localized causes such as calf muscle (commonly known as the calf) spasms are often caused by intense exercise or work fatigue or severe twisting of the tibia, often occurring when lying down or sleeping. 3. Poor sleeping posture, such as prolonged supine position, causing the blanket to press on the feet, or prolonged prone position, causing the feet to press against the bed, forcing some muscles in the calves to be in a state of absolute relaxation for a long time, causing muscle "passive spasms." 4. Fatigue, inadequate sleep, excessive rest, or excessive accumulation of local acidic metabolites can all cause muscle spasms. For example, walking or exercising for too long can cause excessive fatigue in the lower limbs or insufficient rest and sleep, leading to lactic acid accumulation; excessive and prolonged sleep and rest can slow down blood circulation, leading to carbon dioxide accumulation.
