I made the mistake of buying the medicated Otrivin for colds / decongestants even though I didn't have a stuffy nose - just one that is dry & crusty & stiff from the inside. The medicated one is recommended to be used once every 8-10 hours, and since I didn't read the instructions and consistently felt a dry nose, I kept reapplying. This made my nose quite swollen, and irritated it very much.

I found out that saline solution (non-medicated) could be reapplied as often as needed. This was much better for my needs and my swollen nose started to go back to normal. My nose is still a little dry & crusty at times, but its definitely making an improvement !
