If you’re unsure about the cause of your discomfort, it’s always best to seek guidance from a healthcare professional who can provide an accurate diagnosis and recommend the appropriate treatment. Options may include rest, ice, stretching, or even physical therapy. Don’t let pain hold you back from living your best life – take the necessary steps to address it with the help of a medical expert.

Causes of Lower Back Pain

Lower back pain can have various causes, and understanding them is crucial in finding effective treatment options. Here are some of the most common causes of lower back pain:

Muscle Strain

Muscle strain is one of the leading causes of lower back pain. It occurs when the muscles in the lower back, often from overuse or excessive stress, become stretched or torn. This can happen due to improper lifting techniques, sudden movements, or repetitive motions. Muscle strain can cause localized pain and muscle spasms in the lower back.

Lumbar Herniated Disc

A lumbar herniated disc, also known as a slipped or ruptured disc, happens when the soft inner material of a disc pushes through the tough outer layer. When this occurs in the lower back, it can put pressure on nearby nerves, leading to lower back pain. In addition to pain, a lumbar herniated disc may cause radiating pain, numbness, and weakness in the legs.

Degenerative Disc Disease

Degenerative disc disease occurs when the discs between the vertebrae in the spine start to deteriorate over time. This natural aging process can cause the discs to lose their cushioning ability and lead to lower back pain. In some cases, the degenerated discs can also put pressure on the nerves, resulting in radiating pain or numbness.

Spinal Stenosis

Spinal stenosis refers to the narrowing of the spinal canal, often due to age-related changes in the spine. This narrowing can put pressure on the spinal cord or the nerves that branch off from it, causing lower back pain. Symptoms of spinal stenosis may include pain that worsens when walking or standing for long periods, as well as numbness or tingling in the legs.


Scoliosis is a condition characterized by an abnormal sideways curvature of the spine. While most cases of scoliosis are mild and do not cause significant pain, severe scoliosis can lead to lower back pain, especially as the curve progresses. Treatment for scoliosis-related pain may involve physical therapy, bracing, or in severe cases, surgery.

Muscle Imbalances

Muscle imbalances, where certain muscles are weakened while others are overly tight, can contribute to lower back pain. These imbalances can be caused by factors such as poor posture, repetitive movements, or a sedentary lifestyle. Correcting muscle imbalances through targeted exercises and stretching can help alleviate lower back pain and improve posture.

Pregnancy places significant strain on the lower back due to the weight of the growing uterus and hormonal changes that loosen the ligaments in the pelvic area. This can lead to lower back pain, especially in the later stages of pregnancy. Proper posture, gentle exercises, and the use of support belts can help manage pregnancy-related lower back pain.

Kidney Stones

Although kidney stones primarily affect the urinary system, they can cause referred pain to the lower back. When kidney stones move through the urinary tract, they can irritate the nearby structures and cause lower back pain that may radiate to the groin or abdomen. Other symptoms of kidney stones include blood in urine and frequent urination.

Infection or Inflammation

Infections or inflammatory conditions such as osteomyelitis (bone infection) or sacroiliitis (inflammation of the sacroiliac joints) can also lead to lower back pain. These conditions usually require medical intervention, including antibiotics for infections or anti-inflammatory medications for inflammation. Identifying the underlying cause through diagnostic tests is essential for appropriate treatment.

Trauma or Injury

Direct trauma or injury to the lower back, such as from a fall or car accident, can cause acute lower back pain. In some cases, this can result in fractures or sprains in the spine or soft tissue damage. Proper medical evaluation and treatment are necessary to ensure proper healing and prevent chronic pain or complications.

Symptoms of Lower Back Pain

Lower back pain can manifest with a variety of symptoms, indicating underlying causes and helping in the diagnosis. Here are some common symptoms of lower back pain:

Localized Pain

Localized lower back pain refers to pain that is primarily concentrated in the lower back area. It may feel like aching or stiffness and can worsen with movement or certain positions. Localized pain is often associated with muscle strains, degenerative disc disease, or muscle imbalances.

Radiating Pain

Radiating pain, also known as radicular pain, occurs when the pain spreads from the lower back to other parts of the body, typically the legs. This type of pain is commonly associated with conditions such as a lumbar herniated disc or spinal stenosis, as the compressed or irritated nerves cause pain and discomfort that extends beyond the lower back.

Stiffness and Limited Range of Motion

Lower back pain can be accompanied by stiffness and a limited range of motion in the spine. This can make it challenging to bend, twist, or perform certain activities. Stiffness and limited range of motion often occur with muscle strains and degenerative disc disease.

Muscle Spasms

Muscle spasms are involuntary contractions of the muscles in the lower back. These spasms can be painful and may cause a visible or palpable twitching or tightening of the muscles. Muscle spasms commonly occur as a result of muscle strain or imbalances.

Numbness or Tingling

Numbness or tingling sensations, known as paresthesia, can occur in the lower back, buttocks, and legs. This can be a result of nerve compression or irritation from conditions like a herniated disc, spinal stenosis, or sciatica.

Weakness in the Legs

Lower back pain can lead to weakness in the legs, making it difficult to perform activities that require leg strength, such as standing up from a seated position or climbing stairs. Weakness in the legs can be associated with conditions like a lumbar herniated disc or spinal stenosis.
