At present, there is no specific drug treatment for parotitis, and the general antibiotic treatment is ineffective. However, parotitis is a self limited disease, and patients can heal themselves in about 10 days. Clinically, it is mainly symptomatic treatment. First, let the patient be isolated and fully rest in bed until the swelling of parotid gland completely subsides. At ordinary times, the most important thing is to pay attention to the cleanness of the mouth. It is better to eat liquid or soft food, and avoid acidic food to avoid aggravating the swelling of the parotid gland. Rinse your mouth with normal saline after each meal. Drink more water every day to ensure your liquid intake. If the parotid gland swelling is serious, you can use Ruyi Golden Yellow Powder for external application, but you should pay attention to no allergy. If you have encephalitis or orchitis, you must go to the hospital in time.
