Patients with unilateral ear pain may suffer from otitis externa or acute otitis media after catching fire. Patients are advised to take oral Niuhuang Shangqing Pills or Huoxiang Zhengqi Pills or Pudilan Anti-inflammatory Tablets to effectively clear the fire, and they also need to take oral antibiotics for anti-inflammatory purposes, such as roxithromycin or levofloxacin tablets. During the treatment period, the patient must ensure a light diet, no spicy and stimulating foods, and must ensure that the ear canal is clean and avoid water ingress. After a week or so of active treatment, the patient’s pain in one ear will improve, and if necessary, he or she can go to the hospital for further examination and treatment.
