What is the explanation of "tendon package" in traditional Chinese medicine?

It's really hard to explain. The word "tendon bag" accounts for dozens of diseases in traditional Chinese medicine. For example, the tendon on the leg is varicose veins now. Subcutaneous tendon sheath is the manifestation of exogenous evil entering the acupoint. Tenosynovitis of wrist joint of upper limb is also called tenosynovitis. Muscle injury near each joint is called muscle job-hopping. Some special skin diseases have muscle packs. But as far as the special diseases of traditional Chinese medicine are concerned, the horizontal collateral in Huangdi Neijing seems to be the most typical case. If the meridians are full of evidence and empty, there will be horizontal collaterals on the meridians, which will make them impassable and cause diarrhea. This kind of so-called knot-breaking also thinks that there are problems in the structure and function of meridians, which will lead to a knot in one's heart, which is often called job-hopping However, there is a premise that soft tissues must be damaged first, including wind, cold and dampness invading the body as mentioned in Chinese medicine.
