Back strain is a fairly broad category called “soft tissue injury,” which covers muscles, tendons and ligaments. About 80% of back and neck pain is muscle-related.
The stomach muscles, or abdominals, enable the back to bend forward. They also assist in lifting. The abdominals work with the buttock muscles to support the spine. The oblique muscles go around the side of the body to provide additional support to the spine.
Another type of strain relates to spinal ligaments that run in front and in back of the vertebral bodies. Tendons, which also connect muscles in the spine, can develop inflammation, or tendonitis.
Some people believe that part of what makes the back muscles more prone to strain is that they are shorter than other big muscles in the body. The muscles in our thighs that enable us to walk, run and jump are longer and less prone to strain. It’s very unusual to strain a thigh muscle.
Muscles in the back can strain or spasm and form a hard lump, like a charley horse in the leg. Back muscle spasms can be caused by injury and pain, whether the source is muscle strain, or a disc problem. A spasm, defined as an involuntary convulsive contraction of muscle fibers, can be excruciating. The muscle spasm can be steady or come in waves of contractions. Your muscle is sending you a signal that it has been pushed beyond its ability.
A symptom of muscle strain may be an excruciating spasm in the back that is very painful.
Surgery is never appropriate for muscle strain.
As with any muscle injury, it’s natural for an individual to stop moving the injured area and wait for it to heal. Ironically, this is counter-productive. Restricting movement causes the muscle to weaken , become less flexible, and receive less circulation. In fact, gentle stretching and exercise is the best way to resolve the injury by getting it moving and increasing circulation.
