My ball python recently escaped and got some very slightly damaged scales. It didn't looked bad so I didn't preoccupied with it. Later he shed, he shed yesterday, and I found that where his scale where damaged it was way worst that I thought. The shed didn't go off from his injury, should I remove it ? There is some white spot on his body that weren't there. I am not able to find a way to post picture from mobile, so I can't include them for now.

Should I go to the veterinary or what should I do if not?
I don't whow if he could help, but his shed was fine excluding his injury, his terrarium got a hot spot of 88-93f and an overall of 24 (75f) Celsius, but it sometimes droped at 22(72f) Celsius, at night, which I know is too low. At day it goes from 24 to 27(75f to 80f) and it did happened to go up to 29(84f). Moisture is almost always in the range of 50 to 65%
Is my day temperature ok ? And how can I prevent the night temperature to drop in the enclosure?
I am new to reptile keeping.
