Severe and chronic pain can present in different forms among different individuals; however, it typically falls under certain diagnostic criteria.   Chronic pain is typically defined as pain that is ongoing and lasts for a period of three months or longer. This pain can present intermittently or constantly and can vary in degrees of severity.   Severe pain is pain that significantly infringes upon an individual's day-to-day functioning or well-being. It can present in acute or chronic forms and may manifest as burning, aching, shooting, stinging, or throbbing pain. It can be accompanied by other physical symptoms such as stiffness, limited mobility, reduced range of motion, and pain exacerbated by standing, sitting for prolonged periods, or during physical activity.   Chronic or severe pain can interfere with all aspects of an individual's health and wellness, affecting their lives and livelihood by getting in the way of day-to-day responsibilities including work and school, and reducing function in numerous ways.
