Symptoms of Burns
Symptoms of a burn wound vary with the burn’s depth: Superficial burnsare red, swollen, and painful. The burned area whitens (blanches) when lightly touched but does not develop blisters. Partial-thickness burnsare pink or red, swollen, and extremely painful. Within 24 hours (often shortly after the burn), blisters usually develop that may ooze a clear fluid. The burned area may blanch when touched. Full-thickness burnsusually are not painful because the nerves that sense pain have been destroyed. The skin becomes leathery and may be white, black, or bright red. The burned area does not blanch when touched, and hairs can easily be pulled from their roots without pain. The appearance and symptoms of deep burns can worsen during the first hours or even days after the burn. The deepest burns may cause the least pain, because the nerves that sense pain are destroyed.
