Hi, welcome to HCM Based on your symptoms and medications that you got and you still didn t find a solution, I strongly doubt that maybe you might have Nasal Polips. Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They result from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity or certain immune disorders. So, I refer you to an ear, nose and throat (ENT) specialist or an allergy specialist (allergist) for diagnostic tests or treatment. Polyps may be visible with the aid of a simple lighted instrument and diagnostic tests include: 1.Nasal endoscopy. A flexible tube which enables your doctor to perform a detailed examination inside your nose and sinuses. He or she inserts the endoscope into a nostril and guides it into your nasal cavity. 2.Imaging studies. Images obtained with computerized tomography (CT) scan or magnetic resonance imaging (MRI) to pinpoint the size and location of polyps in deeper areas of your sinuses and evaluate the extent of inflammation. or to detect the presence of other possible obstructions in your nasal cavity, such as structural abnormalities or another type of cancerous or noncancerous growth. 3. Allergy tests. skin tests to determine if allergies are contributing to chronic inflammation. 4.Test for cystic fibrosis. If you are diagnosed with nasal polyps, your doctor may suggest testing for cystic fibrosis, an inherited condition affecting the glands that produce mucus, tears, sweat, saliva and digestive juices. hope this will help you, thank you
