Lower Back Muscle Pain
Injuries such as muscle strains are often extremely painful, though they usually improve on their own in a matter of days. Back injuries involving lower back muscle pain may often be quite disruptive to a person's life when the person experiences a back spasm. A back spasm occurs when one or more of the muscles of the lower back go into a continuous contraction, as a result of joint instability, impingement of the nerves supplying those muscles, or because of damage to the muscle itself. As a result of the unremitting muscle contractions involves with muscle injuries such as back spasms, the nerves inside are squeezed, causing the person to experience severe pain. Though these back spasms are often exotically painful, they are usually short lasting, because the muscles in general are proficient in healing themselves, and the pain will often subside in a few days.
There are other circumstances where a person may find themselves in a perpetual cycle of spasm and pain, due to the muscles and nerves reinforcing each other in a negative cycle. In situations such as these, a back injury caused by an overstretching of a muscle in an accident could cause one or more of the back muscles to go into spasm, the spasm could affect the pain sensitive nerves to react by sending pain messages to the brain, and the nerves that branch to the muscles could become more sensitive to pain, causing additional muscle spasms. Here's some more information about lower back muscle pain, and some available treatments.
If the source of lower back muscle pain is due directly due to muscle injuries, they will usually heal on their own. Muscles have a rich supply of blood vessels, and do have the ability to regenerate themselves that the ligaments and synovial joints of the back don't. That being said, some muscle injuries may be slow to heal on their own, and may require some medical intervention to get patients of the path to recovery. Chronic muscle pain is often referred to as myofascial pain syndrome. Myofascial pain syndrome may result in certain groups of muscles being chronically injured, or it may be the body's permanent response to nearby structures (such as spinal discs and facet joints).
Many people with back pain have areas in strained muscles known as trigger points. These are points in the muscle that are especially tense and tight. This tightness in these trigger points may affect the entire muscle, and also transmit pain to points further far from the trigger points origin.
People with muscle injuries such as trigger points and myofascial pain syndrome may choose to miss work and greatly decrease their activities to give their muscles a chance to heal. What science has taught us, though, is that inactivity of strained muscles can prolong certain types of injuries. Prolonged immobility of muscles, in addition to by-products of inflammation, may cause scar tissue to build-up around the muscles, fascia of muscle, and tendons.
Treatments for lower back muscle pain include physical therapy, massage therapy, muscle relaxants, electrical stimulation and ultrasound, and chiropractic.
