Arm muscle twitching

The arms are the most frequently used part of our body. Because they are easy to observe, any abnormalities can be discovered in time. The muscles in our arms make us stronger, but some people find that their arm muscles are twitching. This involuntary twitching is more worrying and may indicate underlying hidden dangers. Don't be too nervous when facing this situation. The key is to understand the situation clearly. So, what is arm muscle twitching?

The twitching of muscles is actually caused by the contraction of a group of muscle cells, which is medically called fasciculations. This type of muscle fascicle tremor can have different sizes and amplitudes. Some small tremors can be felt but not seen, while more obvious tremors can be seen with the naked eye. Muscle twitching is usually benign unless it is accompanied by muscle weakness or atrophy. Most benign muscle twitches have no definite cause. They may occur when you are tired or stressed, and drinking tea or coffee may also aggravate them. This type of palpitations is mostly intermittent, but in a few people it may occur frequently due to physical factors. This condition is similar to eyelid twitching, which is actually a benign fasciculation.

Causes of Fasciculations

Fasciculation is actually caused by the contraction of a group of muscle cells, which is medically known as fasciculation. This type of muscle fascicle tremor can have different sizes and amplitudes. Some small tremors can be felt but not seen, while more obvious tremors can be seen with the naked eye. Muscle twitching is usually benign unless it is accompanied by muscle weakness or atrophy. Most benign muscle twitches have no definite cause. They may occur when you are tired or stressed, and drinking tea or coffee may also aggravate them. This type of palpitations is mostly intermittent, but in a few people it may occur frequently due to physical factors. Many people have experienced eyelid twitching. In fact, eyelid twitching is a benign muscle fasciculation.

However, muscle twitching can also be a warning sign of some neuromuscular diseases. If muscle twitching is accompanied by muscle weakness and atrophy, you should see a neurologist as soon as possible. These disorders include lesions of the motor neurons in the spinal cord, peripheral neuropathy, and a few muscle disorders. These diseases can cause problems in the signal transmission between motor nerve cells and muscles. As a result, the unstable nerves will release some redundant signals, which will cause the muscles to jump. The neurologist must examine the area of ​​muscle weakness, assess the degree of muscle atrophy, and perform nerve conduction and electromyography tests to find the cause. Some diseases can also be treated with medications to reduce muscle twitching.
