The main clinical symptoms of sinusitis are nasal congestion, yellow pus nasal discharge and, in severe cases, headache. In terms of treatment, active anti-inflammation is needed, and patients are allowed to use azithromycin to treat sinusitis. The patient’s allergy history needs to be clarified before using the medication to avoid drug reactions. The patient should also be treated together with eucalyptus pinene enteric capsules to promote the outward drainage of pus from the patient’s sinuses. Normally, azithromycin can be used for about a week and eucalyptus pinene for about half a month. If the patient’s condition still does not improve, it is best to go to the hospital to improve the coronal CT of the sinuses to clarify the specific situation in the patient’s sinuses. If conservative treatment does not work well, you can consider surgery to solve the sinusitis. During the period of treatment with medication, the patient must not smoke or drink alcohol or catch a cold to avoid aggravating the condition.
