What Causes Rhinitis?
Although rhinitis is not usually cause for medical concern, the symptoms can be annoying and distracting, and cause difficulty with getting enough sleep at night. Fortunately, symptoms of rhinitis such as mucus and stuffy and/or runny nose can be treated with home remedies and lifestyle changes such as nasal irrigation and increased hydration, as well as over-the-counter or prescription medications. There are many causes of rhinitis, described below.
