You awakened with a swollen nose in January, a time of the year when there are no grass or tree pollens in the air. That suggests that the inflammation in your nose, called rhinitis, may have begun as non-allergic and is now both allergic and non-allergic. This is common. This is a problem that should be sorted-out by a board certified allergist. It is highly likely that it will be possible to control your problem with the administration of an inhaled nasal steroid.
Good luck.
