PAIN
Pain - a warning signal for the body
Appearing pain informs us that something abnormal is happening in the body. It can manifest itself in physical as well as mental discomfort. It can be chronic, for example: with inflammation of internal organs, degenerative disease, or acute as a result of trauma or infection. The pain can be local as in sore throat, headache or toothache, or widespread as in abdominal or limb pain.
