No, I haven't had a biopsy. I've had this situation for over 50 years and have seen many doctors about it but none of them ever suggested a biopsy. The doctor I have now is doing the best for this situation with the Mupirocin and it works. I use it whenever I feel a soreness in my nose and it keeps it away. I think I'll just stay with this treatment. I'm 78 and at the age of being leery about any new medical treatments in case they mess up something else that's starting to fail in my aging body! It doesn't hurt unless I let it get out of control and become a sore but I don't let it go to that point. I always use the ointment. So I'll just live with it.
