Acute pain: sudden, limited duration. Caused by damage to tissue such as bone, muscle, or organs, and the onset is often accompanied by anxiety or emotional distress.
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.). Chronic pain 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. They can become chronic such as arthritis. Certain treatments such as radiation for cancer, can also cause tissue damage which results in pain.
Nerve damage: The pain that comes from nerve damage could be the result of damage to the central nervous system (CNS), which includes the brain and spinal cord. Or it could result from damage to peripheral nerves.
