Any of these can be blocked, inflamed or irritated, causing sinus pain with or without congestion.Sinus AbnormalitiesThe nasal septum separates one side of the nose from the other. If not straight, this can cause bone spurs that project into the nasal lining. The more crooked (deviated) the septum is, the worse the pain can be. There are other nose structures, such as the middle turbinate (a bone that protrudes into the nasal passage), that, when oddly shaped or sized, can lead to sinus pain without congestion.InflammationThere are also nerves that send and receive impulses from inside the nose, and when these become irritated and swollen they cause tremendous pain in the sinus cavities. The cause of the inflammation could be a result of autoimmune disorders or hormones. In these cas
