Treat a thrown out back by resting, applying ice and/or heat packs and using analgesics, according to Spine-Health. Certain exercises and chiropractic adjustments may also be helpful.
Spine-Health explains that limiting activity for a few days allows the injured areas to heal, but resting for more than a few days causes weakening of muscles that may prolong or exacerbate pain. Alternately applying cold and hot packs to the painful area can relieve inflammation. Gentle exercise helps to condition, strengthen and stretch back muscles relieving pain, making future recurrences less likely, and chiropractic manipulation can relieve pain and inflammation as well.
The Mayo Clinic notes that acetaminophen and nonsteroidal anti-inflammatory drugs can help relieve acute pain. For severe pain, doctors can prescribe muscle relaxants, narcotics and antidepressants. Spine-health.com states that most back pain resolves within six weeks, but if pain persists, epidural steroid injections can provide relief, and surgery is a last resort.
