Lifting too much weight, physical encounters during strenuous sports, overuse, and fatigue of muscles, twisting or bending improperly. Strains and sprains result in soft tissue damage, small amounts of bleeding into the tissue, inflammation, swelling, bruising, and muscle spasms. Normal living can be severely impacted by such injuries. The pain might be sharp, deep, burning, stabbing, or dull. The pain usually lasts a few weeks, but can become chronic if healing is impaired or a repeat insult occurs.
Spinal muscles that support the vertebrae are the extensors like gluteal muscles, the flexors or abdominal muscles, and the side muscles. Once damage or trauma occurs to a muscle, tendon, or ligament, inflammation and swelling lead to pain that is sent via the nerves. As a result, stiffness can develop which changes the way we move around. Likewise, muscle spasms change our posture and position to limit the spasms. Sometimes, it is hard to stand up straight.
