The causes of bruises on the arms vary, and naturally, the elimination methods are also different. Bruises on the arms caused by impacts can be treated through ice packs, medications, etc. If the bruises are caused by injections, local compression, hot compresses, and other methods are needed. It is necessary to deal with bruises on the arms as soon as possible. If they persist, it is recommended to seek medical attention. Methods for dealing with bruises on the arms: ①Ice Pack Treatment: If the patient suffers from bruises on the arms due to external impact, which only involves subcutaneous soft tissue injury, apply ice packs locally for 24 hours to reduce tissue exudation. After 24 hours, apply Jinhuangsan ointment externally and take medications like Zhongtong'an to effectively promote the dissipation of bruises on the arms. ②Compression and Hot Compresses: If the bruises on the arms are caused by short-term compression of the injection site during needle puncture, resulting in subcutaneous bleeding and bruising, apply local pressure to the bruised area for 15 minutes to ensure that bleeding stops. Then, use a hot towel or moxibustion stick for local steaming and physical therapy. Oral medications like Maizhiling and Huoxue Huayu Pills can be taken to promote the spontaneous absorption of blood stasis. ③Egg Application: After boiling and peeling a hot egg, roll it directly over the bruised area to quickly treat the bruising.
