Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. It is highly subjective, meaning no two people feel pain in exactly the same way, even if the cause is similar

. Pain serves as a critical biological signal that alerts us to harm or potential harm, helping protect the body by motivating withdrawal from damaging stimuli and promoting healing

. It can feel like pricking, burning, aching, shooting, or electric sensations and may range from mild to severe

. There are different types of pain:

• Acute pain : sudden, sharp pain from injury or inflammation that usually resolves with healing.
• Chronic pain : pain lasting longer than three months, often persisting beyond the initial cause and affecting quality of life.
• Episodic pain : intermittent pain occurring with certain long-term conditions

Pain involves both sensory and emotional components and is influenced by biological, psychological, and social factors

. It is processed through the nervous system, where specialized nerve fibers called nociceptors detect damage and send signals to the brain for interpretation

. In summary, pain is a complex, personal experience that signals harm or potential harm to the body, combining physical sensations with emotional responses, and varies widely between individuals
