If a patient has swollen lymph nodes below the earlobe, it is recommended that the patient first go to the hospital to complete an ultrasound to clarify the exact extent of the swollen lymph nodes. If the lymph nodes are small, oral treatment can be considered. If the lymph nodes are particularly swollen, patients are advised to consider infusion therapy. Oral medications often include levofloxacin capsules and azithromycin dispersible tablets, and intravenous antibiotics mainly include ceftriaxone injection and cefmetazole injection, and the patient’s condition should improve to a certain extent after active treatment. During the treatment period, patients should try not to touch the lymph nodes under the ear repeatedly with their hands, as this will aggravate the swelling of the lymph nodes. Diet must be light, try not to get anxious and on fire, and reasonable rest and relaxation will help the patient recover, and there will be significant improvement in about a week.
