In case of lumbosacral strain, usually the one or more of the paraspinal muscles which act as the support for spinal cord during movements involving back like lifting heavy objects, walking, bending, twisting etc… are injured. The lumbosacral strain can lead to a minor backache if the injury is not serious. However in case of severe lumbosacral strain, you might not be able to get up from bed. It is very common to develop sprains or strains in back during the daily activities and lumbosacral strain can be easily recovered by taking proper rest or pain treatment medication. Home remedies are also helpful for lumbosacral strain.

Doctor usually tries to identify the cause in case of severe pain by performing complete physical examination and using imaging techniques.

In absence of any serious injury, painkillers with proper rest and home care are sufficient for treatment for lumbosacral strain. Surgery is only necessary when tendons which surround the muscles are completely torn.

Causes of Lumbosacral Strain

Lumbosacral strain is caused due to injury in the muscles of sacral or lumbar areas located around upper buttocks or lower back. The injury is usually a result of a forceful movement and affects the particular portion where tendon and muscles meet known as musculotendinous unit. Thus it is tricky to differentiate between ligament and muscular injury.

Lumbosacral strain is mostly caused when lower back is put under severe pressure. Normally people do not bend their knees and instead bend their back while lifting heavy objects which is one of the causes of lumbosacral strain. An unwanted or sudden movement can also pull the muscles beyond their comfort zone and cause lumbosacral strain. Regular undue stress on muscles can also lead to this situation. Thus people who are related to activities like weight lifting or lifting heavy objects or something which involve bending and lifting regularly have high risk of developing lumbosacral strain.

Any type of feeling of ache in the back which feels like radiating upwards and also downwards to the buttocks is the symptom of lumbosacral strain. Sometimes the pain caused due to lumbosacral strain is so minor that it is felt only during body movements involving back muscles. It is necessary to refer to a doctor if the pain is severe and constant or in case of any swelling in the back.

Mild cases of lumbosacral strain can be easily treated in home with a proper rest for many days to give your back enough time to heal from injury. The use of heat and ice packs alternatively is also effective in getting rid of the painful symptoms. The use of anti-inflammatory medicines like ibuprofen and aspirin is also helpful. Usually it takes two weeks of rest to heal the injury to the muscles after which the individual can return to routine gradually.
