OK
First relax, we have a saying here, it ain't cancer till the Docs says so.
It could be so many things, and even if it is serious you have spotted it early.
I wont say don't worry because you will, but try to stay calm, they chances are it is nothing serious...
Stay with us and keep us informed and don't be afraid to post again between now and your appointment with the ENT... We all know how to worry........
Sunshine... love and hugs
