The most common causes of an itchy throat and ears are allergies, viruses, and infections. However, some environmental factors can also cause itching. The ears, nose, and throat are connected. This means that allergens, viruses, and bacteria can travel between them. Similar membranes line all three, so the same types of infection can affect the throat and ears. Symptoms of a cold or sinusitis could present as an itchy throat and ears. Other symptoms may include a blocked nose and fatigue. Taking OTC medications and drinking fluids can help relieve the symptoms and reduce irritation. If an itchy throat and ears are due to allergies, the symptoms can last longer. A person should see an allergist if the cause of the allergy is not clear or OTC medication is not working.
