What can i do about chronic nasal congestion?

Get evaluated: Significant seasonal/perenial rhinitis can adversely affect quality of life, especially sleep which in turn can affect work performance and life-functions in general. Basic care such as nasal rinse/cleansing to reduce allergen build-up, good air/furnace filters, minimize pet danders. Nasal steroids are best, but you may need more than spray--antihistamine/decongestant. Consult doc. Good luck.
