Chronic pain may arise from an initial injury, such as a back sprain, or there may be an ongoing cause, such as illness. However, there may also be no clear cause. Chronic Pain is one symptom to many chronic illnesses and visible and invisible disabilities.

Other health problems, such as fatigue, sleep disturbance, decreased appetite, and mood changes, also accompany chronic pain. Chronic pain may limit a person’s movements, reduce flexibility, strength, and stamina which eventually causes difficulty in carrying out important and enjoyable activities and hence, leading to disability and despair.
