I touched the toaster trying to get a mini bagel out and it caused a very tiny second degree burn (a tiny blister) right on my thumb knuckle. I wrapped it in wet paper towel for 10 minutes and put a bandaid on. Anything else I should do besides keep the bandaids clean? What is the best ointment and at what point do I apply it? I don’t think it’s worth a doctors visit but also don’t want it to get infected. Would also love to know signs of infection.
