Sneezing and headaches are more likely to be caused by nasal or sinus disease, such as rhinitis, which can cause sneezing and headaches, often accompanied by nasal congestion, runny nose and dizziness. In addition, sinusitis can also cause sneezing and headaches, and can cause a degree of coughing and even fever. Therefore, if you have sneezing and headache, you should have a rhinoscopy or sinus CT examination to clarify. If the sneezing is caused by rhinitis, you can take antihistamines such as cetirizine hydrochloride for relief. If sinusitis is present, treatment with antibiotics such as amoxicillin clavulanate potassium is needed.
