The apple muscle is the muscle and other soft tissues in front of the cheekbone, commonly known as the apple muscle. Pressing pain in the area of the apple muscle may be related to trauma, inflammation and infection, and local muscle spasm. 1. Trauma: If the apple muscle is injured accidentally, it may damage the local soft tissues, which may lead to local bruising and apple muscle pain. Cold compresses can be applied within 3 days after the injury to relieve the pain. 2. Inflammatory infection: If the skin of the apple muscle is slightly damaged, it may lead to bacterial invasion and cause infection. Apple muscle pain caused by inflammatory stimulation may be accompanied by localized swelling. 3. Localized muscle spasm: If you stay up late or laugh for a long time, it may lead to muscle spasm in the area of the upper malleolus, which may cause symptoms of pain in the upper malleolus. It is recommended to consult a doctor for further examination, to clarify the cause with the help of the doctor, and to carry out targeted treatment or therapy if there is pain in the malar muscle.
