Meridian pain is mainly due to a series of causes that lead to meridian blockage, which in turn produces pain, and this is what is often referred to in Chinese medicine. The common reasons for blocking the meridians are as follows: 1. there may be the influence of bruising, such as a trauma to the patient, resulting in localized bleeding, at which time the formation of bruising will block the meridians and cause pain. 2. there may be the influence of qi stagnation, often seen in patients with emotional instability, resulting in qi stagnation, blocking the meridians and possibly producing pain. This pain is often dominated by distension, and sometimes also produces a painful indeterminate situation, that is, there is a wandering situation. 3, may be due to cold condensation, if the body is affected by cold somewhere, will also cause pain, which is due to cold collection and condensation. This is because of the coldness that leads to stagnation. once the body is affected by the evil, it may lead to the blockage of the meridians, which then causes pain. 4. it may also be caused by phlegm. The body’s internal metabolic products are a series of fluids that block the meridians and can also cause pain.
