Defining Pain
The International Association for the Study of Pain (IASP) defines pain as an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage. Pain can impact physical and emotional well-being and is broadly categorized based on its duration and underlying causes.
Chronic vs Acute Pain
Pain that lasts a long time, such as rheumatoid arthritis, peripheral neuropathy, cancer, and idiopathic pain, is called chronic or persistent. Pain that resolves quickly, such as headache or toothache, is called acute.
Acute Pain
Acute pain happens suddenly, starts out sharp or intense, and serves as a warning sign of disease or threat to the body. It is caused by injury, surgery, illness, or trauma and usually lasts from a few minutes to less than six months.
Chronic Pain
Chronic pain is defined as pain persisting for more than three months. It can significantly impair quality of life and daily functioning, often leading to disability.
