Sustained muscle contractions

Introduction Continued contraction of muscles leads to an increase in metabolic rate, but local blood flow is reduced due to long-term contraction, and metabolic substances (such as serotonin) are accumulated, and multiple factors multiply cause pain in the patient. The cause of the disease is not very certain at present, but according to statistics, it may be possible to work in an incorrect posture or do housework for a long time, which may cause cumulative damage, resulting in abnormal secretion of neurotransmitters and hyperalgesia. turn off. Some are caused by long-term stress.

Cause

Muscle fiber pain is a phenomenon of local muscle pain. The cause of the disease is not very certain at present, but the root statistics may be related to long-term work in an incorrect posture or housework, which may cause cumulative damage. Abnormal secretion of neurotransmitters and hyperalgesia of pain are very important. Some are caused by long-term stress. The mechanism of stress causing muscle pain in the body is not clear. Some people think that due to the pressure, the endocrine or immune system changes. Continued contraction of muscles leads to an increase in metabolic rate, but local blood flow is reduced due to long-term contraction, and metabolic substances (such as serotonin) are accumulated, and multiple factors multiply cause pain in the patient. In addition, because soft tissue injuries such as tendonitis and sprains are not treated well, muscle fiber pain can also be caused.

an examination

Muscle fiber pain is the most obvious part of the neck, shoulders, thighs, elbows, and the inside of the knee. It has a significant "pain point". If you press it slightly, it will be particularly painful. If all kinds of examinations are normal, it is necessary to consider whether the disease. According to the survey, muscle fiber pain occurs in young adults who are serious in their work and work well. Among people aged 25 to 45, 1% to 3% have such symptoms and more women than men. As the current work and life are getting tighter, there are more and more such cases. Especially the office workers who work in front of the computer, or play games online or busy with housekeeping, forget the existence of time and ignore the rest, which is more likely to cause these symptoms.

Differential diagnosis

It should be distinguished from the following:

1. Muscular atrophy

The limb needs long-term braking due to injury and other reasons, which inevitably leads to atrophy of the muscle, and the degree of muscle atrophy gradually increases with time. This has a serious impact on the rehabilitation of the patient's function after the injury.

2. Calf muscle atrophy

Calf muscle atrophy refers to calf muscle atrophy refers to dystrophic striated muscle, muscle volume is reduced compared to normal, muscle fibers become thinner or even disappear.

3. Muscle contracture

The clinical syndrome of specific gait and signs manifested by fascial fibrosis and contracture in the muscle and muscle sites.
