Patients with soreness and swelling of the ear root and cheek are generally common for the following reasons First, patients with wisdom teeth growing in the mouth can cause soreness and swelling of the ear root and cheek uncomfortable due to local oral inflammation. Patients are advised to take oral metronidazole tablets, Maizi Ling and other drugs to reduce the local inflammation and swelling. If the medication is not effective, it is suggested that the patient should have the wisdom tooth extracted so that the trauma can be thoroughly hemostatic and anti-inflammatory, thus completely reducing the soreness and swelling of the root of the ear and cheek. If the patient has a parotid tumor, the larger size of the tumor can cause a significant increase in local tension, resulting in soreness and pain in the root of the ear and cheek. Patients can improve the ultrasound examination to clarify the size of the parotid tumor, and it is recommended that they undergo surgery to remove the parotid tumor as soon as possible to reduce the local tension and relieve the soreness and discomfort in the ear and cheek.
