Acute back pain is sudden and typically short-term, lasting up to six weeks, often caused by injury or a sudden event. Chronic back pain, on the other hand, persists for longer than 12 weeks, often with a more gradual onset and a more complex cause. Treatment for acute pain focuses on pain relief and promoting healing, while chronic pain management often involves a multidisciplinary approach to manage pain and improve function.
Acute Back Pain:
- Onset: Sudden and often related to a specific event like lifting, twisting, or an injury.
- Duration: Generally lasts for a few days to a few weeks, sometimes up to six weeks.
- Causes: Muscle strains, sprains, or disc issues related to a sudden injury.
- Treatment: Often includes rest (briefly), pain relievers (NSAIDs, muscle relaxants), physical therapy to strengthen muscles and improve posture, and activity modification.
Chronic Back Pain:
- Onset: Can be gradual or sudden, but persists beyond 12 weeks.
- Duration: Lasts for months or even years.
- Causes: Can be due to a variety of factors, including arthritis, spinal stenosis, disc problems, or even nerve damage. Some causes may not be fully identified.
- Treatment: A multidisciplinary approach is often needed, which may include pain medications, physical therapy, lifestyle modifications, stress management techniques, and potentially other therapies like acupuncture or massage.
