Traditional methods of treatment
If the muscle strain is severe, such as in a complete rupture, it may require surgery to reattach the separated ends of the muscle. Surgery is rarely required, however, for lumbar muscle strains. In most cases, conservative treatments such as stretching, ice, rest from offending activities, and various pain-relieving or anti-inflammatory drugs are used.

Non-steroidal anti-inflammatory drugs (NSAIDS) are still used with great frequency for muscle strains. They help manage the inflammatory reaction from the tissue tearing and also help with pain relief and reducing the subsequent muscle spasm. (Note, though, that detrimental effects of prolonged use of NSAIDS have been a factor in reconsidering this approach. These drugs often have negative gastrointestinal effects and may cause impairment of connective-tissue rebuilding over time.)

Not long ago, bed rest was commonly recommended for lumbar strains. It is now known that immobilization is detrimental to the healing process for these kinds of muscle injuries. Prolonged immobilization appears to cause further muscle splinting and limitations to improved range of motion despite the initial pain relief that may be felt during the rest. What has been found more effective is gentle, protected movement within the client's pain tolerance. This approach is much more commonly recommended. A brace or corset may also be recommended to keep the muscles from being overloaded during the healing phase.
