My 24 yr. old son had this done 8 years ago. He had nose bleeds all the time, mostly during the winter months and at night while in bed. We tried humidifiers, vaseline jelly, sprays, etc. as per his pediatrician. We finally had it done because he started to have them all the time. Getting dressed, eating at the table, at work, in the shower - we finally said that's enough and went to an ENT doctor. I tell you he has not had one since then.
Good luck and feel better.
