Acute pain: Acute pain is sudden, with a limited duration which is caused by damage to tissue such as bone, muscle, or organs, and the onset is often accompanied by anxiety or emotional distress.
Chronic Pain: Chronic pain lasts longer and is generally resistant to medical treatment. It’s usually associated with a long-term illness (such as osteoarthritis, fibromyalgia, etc.). This can be the result of damaged tissue, but very often is attributable to nerve damage, both can cause depression and anxiety
Tissue Damage: Sports injuries like a sprained ankle are often the result of damage to soft tissue and can become chronic such as arthritis. Certain treatments such as radiation for cancer can also cause tissue damage which results in pain.
Nerve damage can result in damage to the central nervous system (CNS), which includes the brain and spine.
