Many orthopedic patients come to the hospital because of pain in limbs or spine, or discomfort. After physical examination and some auxiliary examinations, they may be diagnosed with various diseases, such as aseptic inflammation, muscle strain, osteoarthritis, etc. In the treatment of some orthopedic diseases, we often use some external drugs, such as plaster and ointment. Wantong Jingu Tie is also a commonly used external plaster. For external drugs, we should follow one principle, that is, there is no skin discomfort after external application, because after some plaster is applied, patients may not have allergies or itching for one or two days, However, some plasters may cause local skin itching, pain and peeling after application. Therefore, the duration of application of various plasters must depend on the irritation symptoms of the plaster to the skin, that is, the skin's tolerance. In addition, we should combine the instructions of these plasters, such as whether it is recommended to stick the plaster for 12 hours, 24 hours, or longer, so that we can judge how long it is most appropriate to stick it together.
