HELP!

I haven't been handling my boy recently, especially since he's been ready to shed, but i took him out a few days ago to realize that he had pushed all of the substrate from his hide so the bare glass was too hot from the heating pad under the glass!

I noticed some odd scales-swollen, and figured they were just irritated from the heat, and turned off the pad and put and extra lamp on instead.

I read up on what exactly these odd irritated scales were, and came across info on scale rot and burns, which really has me worried...

I checked on him a few days later (today) to see that the swollen (fluid filled) blistered scales have decreased, but he still has irritated scales that look bloody underneath and even a spot that looks to be the start of scale rot!

Please look at my photos and tell me what you think! what immediate action should I take? I don't even know of any local vets I could take him to, or if i should attempt to clean him myself? I'm a bad mom and I feel horrible for not noticing or handling him sooner
