I had a friend spend 4 months in a burn unit. His opinion on 3rd degree burns is quite different.
I'm repeating what my Drs told me. I wasn't hospitalized for 4 months, but I did have to go to the burn/trauma center multiple times a week for debridement. The 2nd degree burns around the 3rd degrees hurt much worse. Here are the common symptoms of 3rd degree burns. Notice the last one.
The following are the most common symptoms of a full thickness, third-degree burn. However, each child may experience symptoms differently. Symptoms may include:
Dry and leathery skin
Black, white, brown, or yellow skin
Swelling
Lack of pain because nerve endings have been destroyed
