pain receptors
The pain causes due to the damage of cells inside the skin
The skin contains receptors for temperature, pressure and pain.
All vertebrates have general sensors in their skin for touch, pressure, and pain. These are called
exteroceptors
Pressure, Temperature, & Pain
Dermalgia is a medical term that refers to pain in the skin. It may be caused by various factors such as nerve damage, skin conditions, or trauma to the skin. Treatment for dermalgia typically involves addressing the underlying cause of the pain.
Nerves in your skin react to pain, and send messages to your brain. Usually, it is a very quick response, and pain is almost always followed right afterwards.
somatic pain
Pain is caused when nerve endings are exposed - they signal to the brain that there is damage to the skin and tissue, and we feel that as pain.
exteroceptors
Depends on what surgery you are referring to.
