The symptoms of mumps in children can vary from child to child or in severity, and can be divided into local, systemic, and other accompanying symptoms. The mumps may be caused by a viral infection or narrowing of the ducts. If the swelling is severe, it can also cause localized pain, such as localized skin tightness, which is significantly worse when pressed with the hand. Some children may also experience localized skin fever and redness; 2. Systemic symptoms: If the inflammation repeatedly irritates the parotid gland, the inflammatory reaction will continue to worsen and lead to fever in children, and the temperature may even be as high as 39°C. If the fever is prolonged, it can also lead to fever. If the fever is prolonged, it can lead to weakness and head pain, which can affect the child’s life; 3. Other accompanying symptoms: If mumps in children is not treated in time, it can lead to serious swelling of the parotid gland, which can cause difficulty in swallowing and affect the child’s swallowing function and even lead to lack of appetite. If mumps in children is caused by a viral infection, it is necessary to take antiviral medications such as Ribavirin pellets and Pudilan anti-inflammatory oral solution as prescribed by the doctor. If the mumps is caused by narrowing of the ducts, salivary gland endoscopic intervention can be used to flush the parotid ducts and restore patency.
