Definetley get your hotspot down to no higher than like 86 or 87 degrees. And the humidity to around 65%.
What can happen in too dry/too hot of an environment is they can kind of "dry up" inside and you can cause rock hard urates which can cause problems. As well as other skin and respiratory problems. Too warm of temps will also lead to a grumpy animal which can rub on its cage in efforts to get out causing even further problems.
You should be fine though. I see my bloods build up a few urates "back there" that feel like the golf balls mentioned before. But they pass em with ease.
I usually see my animals "go" every 3 to 4 months if that helps in any way.
Get your husbandry straightened out and keep an eye on him, you should be fine.
