Don’t be alarmed. Blisters are soft little pillows of sterile fluid protecting the underlying skin. They are your body’s very own bandaid. Indicating that your immune system is kicking ass. A blister should only ever be punctured if you feel it is restricting your circulation. Blisters can be covered with a non stick wrap. Lazer Erazer will have already done this. Keep the sterile water resistant bandages on for 3-5 days to avoid further injury. This is the lazy legends aftercare. When wounds become infected it isn’t your body doing anything wrong, it’s the outside world coming in. If your bandage falls off don’t stress. Either re-wrap it with something from the chemist or for a more cost effective alternative - Use cling wrap. keep it covered until the blister scabs over.
