Do you know that after working in front of the computer for six hours, the pressure on your fingers is the same as that on your legs when you walk 40 kilometers? The consequence of this is that the same action lasts for a long time, and the wrist will become a "mouse hand" faster and faster. If you often feel numb and dull pain in your hands ... it is very likely that the "mouse hand" found you unconsciously.

What is a "mouse hand"

The so-called "mouse hand" is a popular name, because mouse users are more likely to get this disease. In medical terms, it is "repetitive stress injury". Generally speaking, wrist movements under normal circumstances will not interfere with the median nerve. However, when operating the computer, because the keyboard and mouse have a certain height, the wrist must be bent back at a certain angle, and then the wrist is in a stressed state and cannot stretch naturally.

When the wrist joint is in a state of tension for a long time, the median nerve in the carpal tunnel is compressed, so that the nerve conduction is blocked, and the symptoms of tingling, paralysis and weakness will appear in both hands, and some joints will also find a slight noise when moving. These are the early symptoms of "mouse hand". Then there may be pain that gradually spreads to the shoulders, and the quality of life will be greatly affected; Whether it's opening a can, dialing a phone number or threading a needle, these simplest hand movements will make you feel very tired.

In fact, the slight damage to our finger joints and nerve fibers is no less costly than the pain in our leg muscles after a whole day's travel. And with the aggravation of the disease, "mouse hand" will gradually evolve into local symptoms. A series of neck-shoulder-wrist syndrome may occur if the mouse position is too high, too low or too far away.

How to treat "mouse hand"

According to the investigation of medical experts, "mouse hand" is often caused by mistakes in work and frequent use of the mouse. So, what can we do with the mouse hand?

This value can tell the doctor that your nerve is damaged and can help diagnose the type of disease. According to the symptoms, doctors often suggest that you use rheumatism ointment or hand joint splint which can prevent manual operation.
