What causes finger cramps?

Protecting the health of fingers is something that needs to be taken seriously in life, because the health of fingers can be easily affected by various factors, causing great damage to the fingers. For example, many people have experienced symptoms of finger cramps, which has a great impact on people's health. Let's take a look at the causes of finger cramps. I hope everyone can understand.

Cramps are medically called spasms. When it comes to calf cramps, people often associate it with the limbs getting cold while swimming, but there is no "cold" during sleep, so people think it is caused by calcium deficiency. However, for many people who suffer from calf cramps, after taking calcium tablets and drinking calcium-rich milk, the symptoms of cramps not only did not improve, but became worse.

In fact, there are many reasons that cause muscle spasms, but people tend to ignore the factor of magnesium deficiency. In fact, muscle spasms in many patients are caused not by calcium deficiency but by magnesium deficiency. Magnesium is an important cation in cells. It works with ATP and other substances in cells to activate many important enzymes. If there is insufficient magnesium in the blood, the activity of certain enzymes will decrease, potassium ions will overflow from the cells, and the excitability of the nerves and muscles will increase due to insufficient potassium in the cells, making muscle spasms more likely to occur. In this case, blindly supplementing calcium is like adding insult to injury. Because calcium and magnesium have antagonistic effects, calcium can reduce the activity of magnesium in cells, causing magnesium deficiency muscle cramps to become more severe.

Reason 1: Too much use of fingers

The reason for repeated finger cramps may be maintaining the same posture for too long, such as using a mouse, tablet, or mobile phone for a long time, or for people who need to use their fingers to work. If the posture is incorrect or there is no timely rest, the fingers are prone to cramps.

Reason 2: Problems with the nerves that control the hand muscles

Finger cramps can also occur when there is a problem with the median nerve, ulnar nerve, or radial nerve that controls the hand muscles.

Reason 3／Compression of cervical nerves

Patients with bone spurs or herniated discs in the cervical spine may suffer from finger cramps due to compression of the cervical nerves.
