Celia are tiny hairs in our nostrils that purifies the air before it enters the lungs. The celia also warms the cold air before entering our lungs. Try just using nasal saline about
3 times a day (about
2 sprays each nostril). That might just help ... you may just have a sinus infection or nasal congestion that is making your ability to smell be "off" a little. Good luck!
