Pain can be classified into two main types: acute and chronic. Acute pain is a sudden onset of discomfort, often resulting from injury, surgery, or illness. It typically lasts for a short duration and serves as a warning signal for the body to protect itself. In contrast, chronic pain persists for longer periods, often lasting for months or even years. It may arise from conditions like arthritis or fibromyalgia and can significantly impact daily life. Understanding these types helps in determining appropriate treatment and management strategies for individuals experiencing pain.
