Parotid nodules are mainly caused by blockage of parotid ducts and retention of secretions, which may result in fever, anorexia, localized pain and other symptoms. Each patient’s physical condition is different, so the symptoms of parotid nodules are also different. Some patients with parotid nodules may have localized pain, swelling and hardness, as well as fever, anorexia, and broken infection. Parotid nodules need to be treated according to the size and severity of the nodule. If the parotid nodule is small, it can be left untreated for the time being; if the parotid nodule is large, it needs to be operated in time to remove the parotid nodule. Normally, you need to pay more attention to your diet and keep a light diet.
