The spine is supported by muscles and ligaments, may become strained or weakened. This can lead to muscle spasm and resulting back pain. Most back pain can be caused by sprain, muscle weakness, tension, or arthritic conditions. Chronic muscle strain may be a result of poor posture or overuse of muscles. Lifting and turning at the same time, lifting too much weight, or twisting into an awkward position may strain the involved muscle group.
Strains can occur in any area of the body - back, neck, leg, shoulder, etc.
Muscle strain can also be caused by lack of adequate warm-up exercises, certain traumatic conditions, and being overweight. Bed rest is often recommended in order to allow the injured area to heal without any further stress. The amount of bed rest prescribed by your doctor will vary according to your condition. Your physician may also recommend dry or wet heat. Occasionally , cold, such as ice massage, may be effective in the temporary relief of acute muscle spasm.
