I like all you have been experiencing the same symptoms. I had surgery about 1 year ago on my nose. I thought that was the problem. Anyways I kept goggling everything I can think of "Smoke in the nose" Nose has burning smell" Nose smell like cigarettes' etc. I don't smoke so knew that couldn't be the problem. I hate medicine and try to use everything natural. This helped and almost eliminates every symptom (Headache, Eyes burning and Smell)
Here you go:
First go to a Drugstore you have.
Go pick up this thing called "*Sinus Rinse*" Do a search on google to make sure you get the right one. Under 10 bucks. Buy the extra packets you might need them. Use this for Exactly One week. 2 times a day. in the morning when you wake and after dinner.
Last step. Go to any (Pharmacy) and pick up some Saline Nasal Spray -under 3 dollars or whatever brand you prefer. I chose the cheapest. Use it to moisturize your nose lining. I use it like 6 to 7 times daily. It works wonders.
That's it. enjoy and God bless
Happy Smelling Again!
