Hi Phil,
New poster here. I'm 64 and I have HHT. 100+ cauterization's over the last 40 years to my nose. Nothing left but scar tissue and a rather LARGE hole in the septum. I did have my tongue lasered 2 years ago. A red spot developed in the center and in 3 months it was the size of a pea. Of course it broke open during a dinner engagement and freaked out the whole restaurant. It was the worst bleed in memory. Looked like Gene Simmons of "KISS". I used powdered ALUM to get it stopped. Two days later laser surgery. No Problem, easiest of all cautery's. Very little pain and the spot disappeared completely. I have cauterized my, nose, scalp, ears, mouth, colon over the years. NO alcohol, aspirins, or blood thinners of any type. In retrospect, I would not have done any cautery to start with. Management with polysporin is the order of the day. No more cautery for me if I can help it. I have a mild case of HHT compared to others on this thread. My father had a FAR worse case of HHT than me and lived to 87. He used a mixture of Alum powder mixed with polysporin to coat the inside of his nose. He died of a unrelated problem. My heart go's out to all with this dreaded disease.
Regards Brian
