Actually, it's best to pop it, remove the cap, then care for the raw area with an antibiotic ointment and keep it covered. The fluid (plasma) can get infected under the blister cap and make things much worse. I know a thing or two about burns.
And since we're sharing burn stories, I was searing a piece of tuna, and had the oil at flash point (probably around 600). I jerked my hand back to avoid hitting a dish guy with the pan and the oil poured all over the back of my and, from the thumb and forefinger to the wrist. Took two shots of morphine at the hospital to get the pain under control, and it took the plastic surgeon a week to decide it didn't need a skin graft. Fifteen years later, and I still have a scar over the back of my hand.
