Muscle soreness often does not appear immediately after exercise, but appears on the second or third day, and gradually relieves after 2 ~ 3 days. The pain peaked 24 ~ 72 hours after exercise, and basically disappeared after 5 ~ 7 days. When you do the same exercise again or continuously, the symptoms of muscle soreness will be obviously alleviated or not produced.
Muscle soreness lasts for 24 to 72 hours after exercise. If it exceeds this time range, it is likely to be muscle spasm. Once muscle spasm occurs, it is necessary to deal with it in time and seek medical advice in time, otherwise it may cause muscle damage.
Extended data
Muscle soreness can be caused by sports, infectious diseases and other diseases. Its theory is:
① Tissue traction: muscle injury. ② Muscle spasm: Repeated muscle spasm. ③ Connective tissue: The connective tissue of muscle is damaged (such as tendon). In fact, chronic muscle soreness is caused by muscle injury and division.
Etiology and common diseases
1. Movement
Muscle aches that occur from a few hours to 24 hours after exercise generally last about 1 ~ 3 days. The reason is nothing more than muscle injury, muscle spasm or abnormal connective tissue. It is generally believed that abnormal connective tissue is the biggest cause of muscle soreness.
2. Infectious diseases
For example, Middle East respiratory syndrome, rickettsia spotted fever in Siberia, legionnaires' disease, Pontiac fever, mumps, malaria and other diseases can cause persistent high body temperature, which can be as high as 40℃ or above, accompanied by repeated chills, muscle aches and other symptoms.
3. Other diseases
Such as repeated tension injury, uveitis with Wegener granuloma, beriberi heart disease, etc. Muscle aches often occur.
