Re: Nose Sores ???
I have had periodic painful sores in my nose for 30 years, that looked like small blisters, and hurt like the dickens for at least 2 weeks. There is always a strange sensation a day or two before that lets me know when a blister is forming. In me, they are triggered by chocolate or getting too hot. And stress. However, when I was at my dermatologist a couple of years ago, I had her do a culture, and they found an overgrowth of staph in my nose causing the painful blisters. They told me to use a triple antibiotic cream from the drugstore, and it got rid of it. It came back a couple of times, but I used the cream, and now haven't had it in a while. Seems like I had to use it several times a day for 2-3 weeks.
There are a lot of different things it could be, you might want a doctor to do a culture.
