I think my cat burned her nose

I think my 2 year old cat burned her nose on my reptile heat lamps yesterday :(

We don’t have much money so we decided to keep an eye on it. I have an aloe plant so we’ve been putting tiny amounts of aloe from it on there. She doesn’t seem to mind.

I can’t attach any images, but yesterday it was bright red, today it looks scabby? Still red.

Should we take her to the vet? The soonest my vet could see her is next Thursday (27th).

Any advice is appreciated.
