No problem-o. I did the same when I had sores, and was concerned about the consequences. But when your nose hurts, it's tough to sleep.
FWIW, the Neosporin didn't seem to do anything to cut down the inflammation. The sores had to crust over and heal on their own. That's what goaded me to seek out an alternative. Someone on this great forum recommended Ayr Gel, so I bought a tube and it worked wonderfully. But, in my line of work, I read labels compulsively, and I realized that there were other much cheaper alternatives. So when the Ayr ran out, I got a tube of Astroglide (and some panty liners, but that was for another mask-related project I was working on
) and found it's even better than Ayr gel because as it dries out, it becomes sticky, which holds the nasal pillows in place and reduces the tendency of air to leak out.
In addition to the above, most guys have rather hirsuite nasal passages. I've often thought some guys could grow a convincing moustache simply by not trimming their nose hairs. And those hairs, when they get too long, are responsible for lots of nasal pillow leaks. Fortunately, Astroglide becomes thick enough about 1/2 hour after application to completely seal those leaks, allowing me to sleep in blissful leak-freeness!
