When I quarrel with others, my hands always shake with excitement

When people's emotions change, their bodies will also show some symptoms. When they are happy, they will laugh out loud; when they are sad, they will cry... These are all normal. However, some people say that when they quarrel with others, they always get excited and their hands tremble, as if they are sick. What's going on? In fact, it is common to have shaking hands when you are emotionally excited. It is not a disease and does not require treatment, but it still has an impact on your physical health.

There are two main types of hand tremors:

1. Essential tremor. The cause of this disease is unknown and it mainly affects the upper limbs and head. The main symptom is hand tremors when doing fine movements, such as writing, holding chopsticks, buttoning, etc. Hand tremors are more obvious when you are emotionally nervous or tired, and they are reduced or disappear completely when you relax or rest. Symptoms may be alleviated after drinking alcohol. Neurological examination showed no abnormalities except hand tremors. Currently, the most effective treatment for this disease is drug therapy. Taking medicine can improve symptoms, but they will relapse after stopping the medicine, which is the so-called "treating the symptoms but not the root cause." Essential tremor progresses very slowly or not at all and has little effect on daily life. 2. Parkinson's disease. This is a degenerative disease that occurs in the elderly. In addition to hand tremors, it is also accompanied by symptoms such as slow movements, limb stiffness, and poor balance. If not treated, symptoms will become more severe. This disease requires the help of a specialist to diagnose and treat. Hand tremors are divided into physiological hand tremors and pathological hand tremors.

Physiological hand tremors have small amplitudes and fast speeds, and often occur when the hand is stationary. They are small, fast, and irregular tremors. Physiological hand tremors often occur when one is nervous, afraid, etc. Hand tremors occur when you are emotionally excited, in severe pain, or extremely tired. Once the above causes of hand tremors are eliminated, the hand tremors will disappear.

Pathological hand tremor, medically known as "tremor", refers to the involuntary shaking of the hands, which is often permanent. There are two main types of hand tremors: static hand tremors and dynamic hand tremors. Among them, static hand tremor is the hand tremor that occurs when the muscles are completely relaxed, that is, in a quiet state. This type of hand tremor disappears during sleep, with a frequency of 4-6 times per second and a relatively regular pattern. It is a typical disease such as Parkinson's syndrome. Sports tremor is a tremor that only occurs during exercise, and the tremor becomes more severe when the movement approaches the target. For example, when a doctor performs the finger-to-nose test on a patient, he asks the patient to straighten his forearm and then point his index finger at the tip of his nose. The closer the tip of the index finger is to the tip of the nose, the more obvious the hand tremor will be. Motor tremors are irregular, with large amplitudes, and are aggravated by emotions. They are common in lesions of the cranial nerves and upper limb nerves.

Common diseases that cause pathological hand tremors clinically include upper limb nerve diseases and injuries, brain tissue diseases, and drug-induced hand tremors.
