If the parotid area is swollen, it is a disease of the parotid area. For example, acute suppurative mumps can present with symptoms such as redness, swelling, heat and pain in the parotid gland area. Routine blood tests may show a significant increase in total white blood cells and an increased neutrophil ratio, requiring treatment with sensitive antibiotics. Acute mumps can also be caused by a viral infection, which is contagious and needs to be isolated. For viral infections, there are no specific antiviral medications, but mainly symptomatic treatment. It may also be caused by a parotid tumor, which requires surgery. If you are middle-aged or older, you should also consider malignant tumors of the parotid gland. The specific situation requires a visit to the stomatology department, and after a clear diagnosis, treatment should be carried out under the guidance of the doctor.
