I burned myself on my oven and now the injury has turned into a water blister. Should I pop it? Should I put a bandage on it?

It is not recommended to pop a blister. It is best to leave it alone and avoid applying any creams to it. Letting the blister heal on its own by keeping it exposed to air is usually the best course of action. If redness, heat, or increasing pain develops around the blister in the coming days, it may be necessary to seek medical attention.
