The comfort you are looking for is to get rid of sinus problems. You will get used
to the burning sensation, to the point where it doesn’t bother you anymore.
The burning will not damage your sense of smell. In fact, it will improve it. I keep a small bottle of Dr.Bronner’s Peppermint Pure-Castile Soap in the shower.. When I’m sick I can barely smell it, but after a saline flush the smell will be strong enough to give me a jolt.
