The most common treatment for a lower back muscle spasm is gentle movement, heating pads applied to the area, and over-the-counter pain relievers, such as non-steroidal anti-inflammatory drugs (NSAIDs), which help to reduce swelling and inflammation. Aspirin and ibuprofen are usually effective at easing the pain of muscle spasms. Once the pain lessens, stretching and exercise can help to strengthen the muscles of the lower back and may help to prevent back spasms in the future. Practicing good posture, both when sitting or standing for long periods of time, is also important.
Lower back muscle spasms often occur when the muscles are overworked or overstretched, often because a person lifts heavy things incorrectly, although simply twisting or bending too quickly can injure the back. Some people get spasms for no reason, and others find that they worsen if they sit in a chair in front of a computer all day. Though identifying the cause is certainly helpful in order to prevent future issues, the most important thing to do is to treat the spasm. If the muscle pain continues to worsen, or the frequency of the back spasms increases, sufferers should visit a medical professional to rule out any more serious spinal problems.
Even though it may be tempting for a person to lie down to relieve lower back pain, this can put more pressure on the lower back and make the spasm worse. Some people find that, if they must lie down, bending the knees can help, though it is best to get up and sit in a comfortable, supportive chair or even to walk around slowly to try to release tension in the muscles. Applying warmth, such as through a heating pad or a hot shower, can also help to relax the muscles and relieve pain. It is also best to take an anti-inflammatory pain reliever as soon as the first twinge occurs; if over-the-counter medication doesn't help an individual, a medical professional may be able to prescribe a stronger muscle relaxant.
To prevent lower back muscle pain in the future, a person should be sure to take frequent breaks at work and not stay in the same position for hours every day. He should get up and move or go for a walk, and strengthen the lower back with targeted stretching and exercises, since muscle spasms are often caused by muscles that are weak and unused. Some people find that yoga is helpful for stretching and strengthening the lower back muscles.
