Hello,
I think the first thing you should do is get down to the doctor straight away regardless of the Class 1!! It could prove to be something serious and that may cause serious problems in later life. As your quite young now, it would be wise to get it checked and hopefully get it cured as soon as possible.
The ear is an extremely sensitive part of the human body and it needs to be in tiptop condition to get the Class 1 issued. Best of luck and keep us posted!
Cheers,
John
