I was baking with the oven set to 325F. I reached in to remove a pie and touched the element with my wrist near the scaphoid bone. I felt the element but not the burn. I pulled away and ended up with a blistering burn. The spot did not hurt afterward either. I have put no lotion or burn treatment on the spot which now, two days later, is red but I the blister disappeared without breaking the skin. It still does not hurt (unless I rub it vigorously).
Should I be concerned?
