Pain localizations

Back pain in the lumbar spine often occurs only on one side, for example on the right side. There are various possible causes for this, which in most cases are harmless and can be improved by regular strengthening exercises. This is because back pain on the right side is often caused by muscle tension or pinching of a nerve.

The latter often causes pain that extends into the right leg, because many nerves come from the lumbar spine and run down into the leg. A so-called spinal canal stenosis can also lead to these symptoms. This is a narrowing of the spinal canal, which occurs mainly in the lumbar spine.

Local inflammation or, for example, an abscess, i.e. a cavity filled with pus, can also be a possible cause of back pain on the right side. If the pain is severe over a longer period of time, a lateral herniated disc or a bulging of the disc should also be considered. Diseases of the right kidney, such as inflammation of the renal pelvis, can also lead to back pain on the right side in the lumbar spine area.

Here, other symptoms such as fever or bloody urine often occur. Back pain in the lumbar spine area often occurs on one side only and many patients complain of pain in the lower left back. There are various possible causes for this.

These include tension or strains of the muscles, which can occur during sports, for example. Often the strongest hip flexor, the so-called ilipsoas, is tense, which compresses the surrounding nerves. This causes the pain to radiate into the left leg.

Depending on the extent of this nerve compression, this pain can also become worse and better depending on how you walk. Spondylolisthesis, i.e. spondylolisthesis with instability of the spine, often occurs in the lumbar spine and can lead to unilateral pain on the left side.A frequent cause is also the herniated disc or the bulging of the disc, which, depending on its severity, can also cause pain mainly on the left side. In some cases, diseases of the left kidney can also cause back pain at the level of the lumbar spine.

In case of suspicion, other symptoms such as fever and blood in the urine should therefore also be considered. The intestines can also cause back pain in the lumbar spine on the left side in the case of severe digestive problems. Back pain of the lumbar spine often occurs on both sides.

There are also different causes for this. For example, everyday problems such as poor posture or weak muscles can lead to complaints. The intervertebral discs most often cause pain in the lumbar spine area in the case of bulges or shifts.

In extreme cases, fractures or tumors that press on the spinal canal are also conceivable. However, this is rather rare. The kidneys can also be a possible cause, although it is more common that kidney disease is only unilateral.
