Certain over-the-counter medicines can help alleviate and reduce the severity of sinus symptoms. In addition, home remedies may help acute cases of infections, headaches, or allergies. However, many patients do not find adequate relief with over-the-counter treatments alone. In some situations, patients may have an undiagnosed sinus disorder that does not respond at all to non-prescription medicines. Seeing a sinus specialist can determine the causes of your symptoms so you can understand which treatments are ideal for your condition.
