Discussion: Physical pain - My suggested definition. (Without using synonyms for pain)

In patients with chronic diseases of the digestive tract, pain originates from prolonged damage to the tissue of the walls of the small and large intestines (for their entire length). The more comprehensive the damage (in quantity and intensity), the more pain there is.

"Pain is a short or continuous alarm sensation caused by temporary or permanent cell damage (above a certain threshold) in tissue with sensory nerves (nociceptors) ." Pain is a part of the self-defense mechanism.
If you look for definitions for physical pain, you will find that they are not uniform.

"Inflammation - is a short or continuous immune response caused by temporary or permanent cell damage intended to rehabilitate the damaged tissue."
