Pain can vary from mild discomfort to strong pain. It occurs when body tissue becomes inflamed or is damaged. This stimulates local pain sensors which trigger the central nervous system and cause you to feel pain. This is a natural part of the body's defence system and is designed to slow you down to try and help minimise further harm.
The causes of pain are many and varied, but there are a few common conditions that most of us will experience at some stage in our lives.
