Lower Back Pain: Clinical Meaning

Kidney Stones

Kidney stones are hard mineral deposits that form in the kidneys and can cause severe pain when passing through the urinary tract. The pain typically starts in the back or side and radiates to the lower abdomen. Increased fluid intake is key to prevention.

Ankylosing Spondylitis

Ankylosing spondylitis is a type of inflammatory arthritis primarily affecting the spine and sacroiliac joints. It causes chronic pain and stiffness in the lower back and can lead to fusion of spinal vertebrae. It is more common in men.

Prostate Cancer

Prostate cancer is the most common cancer in men, growing in the prostate gland. Most cases are slow-growing, but aggressive forms can spread rapidly; PSA screening and biopsy are key diagnostic tools.

Cervical Cancer

Cervical cancer is caused primarily by persistent HPV infection and is highly preventable with vaccination and regular Pap smears. It develops in the cervix and is one of the most common cancers in women globally.

Kidney Cancer (Renal Cell Carcinoma)

Renal cell carcinoma is the most common kidney cancer in adults, often discovered incidentally on imaging. Symptoms include hematuria, flank pain, and a palpable mass; smoking and obesity are key risk factors.

Sciatica

Sciatica refers to pain radiating along the sciatic nerve from the lower back through the hip and down the leg, typically caused by a herniated disc or spinal stenosis compressing the nerve root. Most cases resolve with conservative treatment.

Herniated Disc (Slipped Disc)

A herniated disc occurs when the soft inner material of an intervertebral disc protrudes through a tear in the outer ring, compressing nearby nerves. It causes radicular pain (sciatica for lumbar disc; arm pain for cervical disc), numbness, and weakness.

Scoliosis

Scoliosis is an abnormal lateral curvature of the spine, most commonly idiopathic and developing during adolescence. Mild curves are observed; progressive curves require bracing or surgical correction to prevent cardiopulmonary compromise.

Uterine Fibroids

Uterine fibroids are benign smooth muscle tumors of the uterus, causing heavy menstrual bleeding, pelvic pressure, and urinary symptoms. They affect up to 70% of women by age 50; treatment ranges from watchful waiting to medication or surgical removal.

Adenomyosis

Adenomyosis occurs when endometrial tissue grows within the muscular wall of the uterus, causing heavy, painful periods and an enlarged uterus. It often coexists with endometriosis; hormonal therapy and hysterectomy are treatment options.

Reactive Arthritis

Reactive arthritis is joint inflammation triggered by an infection elsewhere in the body, usually intestines, genitals, or urinary tract. The classic triad includes joint, eye, and urethral inflammation.
