Hello Ali,I think we will all sympathise with the feeling of embarassment you speak of when out in public with a nose bleed.
I must confess That it is something I have never been able to come to terms with 100%,and I have bled now for more years than I care to remember.
But you have youth on your side and will for sure get by with a will,as you have your whole life to look foward too.
You must try the laser treatment but do not overdo it,same with standard cauterisation,if it does no lasting good give it a wide birth,I run a mile now whenever it is mentioned.
The best treatment is finding a way that suits your nose to be more comfortable and thus less epitaxis,keeping the nasals moist,I use distilled water,neptosin,and e45 cream.(not at the same time he.he.)
A lady in the states on another web site for hht swears by preperation H cream and has used it for years.
So I suppose whatever suit you best is what to use.
Anyway Ali pleased you have joined up,it is nice to know your not alone.
Take care be happy........BOB..
