Is my phalaenopsis's leaf infected at the scratch and should i worry about it?

[Lilnuge]

I am sort of new at this so please help, I got a phalaenopsis a few months ago, when I got it, its leaf already had the scratch on it. The scratch had been a tan/brown color but it recently turned white with a brown/black middle. Being new at this, I don't know if the scratch is infected or what is wrong with it.

I have pictures of the scratch but my computer wont let me attach them. if you want to see it I can email them to you.
