Sinusitis is basically the swelling of the lining in the nose and in the sinuses. The lining is mucosa that basically gets inflamed when we have an episode of sinusitis. Signs of sinusitis both chronic and acute include headache, sinus pressure, tenderness around your nose, your face, some people get drainage, ear pressure. Sometimes we also get pain that radiates down to our teeth or when people bend over, they get a throbbing, pressure feeling. This is evidence that there’s obstruction in your sinuses from basically that build up, or thickening, of the mucosa with mucus production. Allergies definitely can play a role. When you breathe in those allergens, they can land on mucosa and cause inflammation and swelling. That, in turn, makes mucus production, and you get that build up that I was kind of talking about, and then those symptoms. How do I treat this? Definitely get allergy tested. If allergies play a role we can either do skin testing or blood work to see if you’re allergic. If you are, there are different medications you can use. Antihistamines are great because they block the receptors that can actually cause some of the inflammation. We can use intranasal steroids, which are like Flonase, Nasacort, Rhinocort, which actually work locally and allow the inflammation to come down. And then we get to immunotherapy. So if you’re allergies are causing this, we have immunotherapy. There’s subcutaneous immunotherapy, which is known as allergy shots, and we also have sublingual immunotherapy, which our clinic specializes in. Basically this targets your allergies and treats them so you don’t get that inflammation response, that mucus build up. You don’t get those symptoms of the pressure or the pain.
