Snake nose injury from rubbing.

[Eye]

My snake hurt himself by rubbing so much on the top of the tank. I have cats that have left him alone until last week and I think that may have stressed him out so they're locked out when I'm at work now. His poor little nose looks like it's been rubbed off, and he kept going right to the top where the heat lamp so I think he may have burned it too. Ive since propped it up on rocks so it's not directly on the cage. Do I need to get him to a vet ASAP for antibiotics or will it heal up on its own?

I have a 72"x24x24 PVC enclosure on the way. This tank was always meant to be temporary and he's finally outgrown it big time. He has an extremely healthy appetite I fed him 2 rats a few days apart to get him to relax and that's worked. he's been sleeping off his meal.

He's about 6 ft long with a 10" girth and other than the nose injury he seems very healthy. Has anyone else had a snake that's had this injury? This picture actually looks a little worse than what it really looks like. I don't want to take him out and bug him since he's still digesting.
