Back Pain: Clinical Meaning

Osteoporosis

Osteoporosis is a condition where bones become porous and fragile, greatly increasing fracture risk. It is often called a 'silent disease' because bone loss occurs without symptoms until a fracture happens, most commonly in the hip, spine, or wrist.

Depression

Depression is a common and serious mood disorder causing persistent feelings of sadness, hopelessness, and loss of interest in activities. It affects how a person thinks, feels, and handles daily activities. Effective treatments include therapy and medication.

Pancreatitis

Pancreatitis is inflammation of the pancreas, which can be acute (sudden) or chronic (long-term). Gallstones and heavy alcohol use are the most common causes. It causes severe upper abdominal pain that may radiate to the back, nausea, and vomiting.

Gallstones

Gallstones are hardened deposits of digestive fluid that form in the gallbladder. They can range from sand-grain size to golf-ball size. Many are asymptomatic, but when they block a duct they cause severe 'biliary colic' pain in the upper right abdomen.

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.

Prostatitis

Prostatitis is inflammation of the prostate gland, which can be caused by bacterial infection or other factors. It causes pelvic pain, difficult or painful urination, and sometimes fever and chills. Chronic prostatitis is the most common form.

Endometriosis

Endometriosis is a condition where tissue similar to the uterine lining grows outside the uterus. It causes chronic pelvic pain, especially during menstruation, and can lead to infertility. It affects approximately 10% of reproductive-age women.

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.

Pancreatic Cancer

Pancreatic cancer has one of the lowest survival rates of all cancers, largely due to late-stage diagnosis. Symptoms include jaundice, weight loss, abdominal pain, and new-onset diabetes; most cases are adenocarcinomas.

Aortic Aneurysm

An aortic aneurysm is a bulge in the aorta wall that can rupture and cause life-threatening hemorrhage. Abdominal aortic aneurysms are most common and often asymptomatic until rupture; smoking and hypertension are major 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.

Transverse Myelitis

Transverse myelitis is inflammation across both sides of the spinal cord, causing weakness, sensory changes, and bladder dysfunction below the level of inflammation. It can be idiopathic or associated with multiple sclerosis or neuromyelitis optica.

Urinary Tract Infection (UTI)

Urinary tract infections are caused by bacteria entering the urethra and bladder, causing painful urination, urgency, and frequency. Women are significantly more affected; E. coli causes about 80% of cases.

Vitamin D Deficiency

Vitamin D deficiency impairs calcium absorption and bone mineralization, causing bone pain, muscle weakness, fatigue, and increased fracture risk. It is extremely common globally due to limited sun exposure and dietary insufficiency.

Hydronephrosis

Hydronephrosis is dilation of the renal collecting system due to obstruction of urine flow (kidney stones, stricture, tumor). If bilateral or complete, it can cause acute kidney injury; treatment addresses the underlying obstruction.

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.

Ovarian Cysts

Ovarian cysts are fluid-filled sacs on or in the ovary, most of which are benign and resolve spontaneously. Symptomatic cysts cause pelvic pain, bloating, and pressure; large or persistent cysts may require surgical evaluation.

Pleurisy

Pleurisy is inflammation of the pleural membranes surrounding the lungs, causing sharp chest pain that worsens when breathing deeply or coughing.

Burnout Syndrome

Burnout is a state of chronic stress leading to physical and emotional exhaustion, cynicism, and feelings of ineffectiveness. The WHO recognizes it as an occupational phenomenon.

Psoriatic Arthritis

Psoriatic arthritis is inflammatory arthritis affecting some people with psoriasis. It causes joint pain, stiffness and swelling ranging from mild to severe with potential for joint damage.

Premenstrual Syndrome (PMS)

PMS encompasses physical and emotional symptoms occurring before menstruation, resolving with the onset of the period. It affects up to 75% of menstruating women to some degree.

Kidney Infection (Pyelonephritis)

Pyelonephritis is bacterial infection of one or both kidneys, usually ascending from a bladder infection. It requires prompt antibiotics to prevent kidney damage and sepsis.

Pelvic Inflammatory Disease (PID)

PID is an infection of the female reproductive organs, usually caused by sexually transmitted bacteria. Untreated, it can lead to infertility, ectopic pregnancy, and chronic pelvic pain.

Aortic Dissection

Aortic dissection is a life-threatening emergency in which the inner layer of the aorta tears, allowing blood to surge between the vessel walls. It typically presents with sudden, severe tearing or ripping chest or back pain radiating to the back, and requires immediate surgical evaluation.

Cauda Equina Syndrome

Cauda equina syndrome is a serious neurological emergency caused by compression of the cauda equina nerve roots in the lower lumbar spine. It presents with severe low back pain, saddle anaesthesia, progressive leg weakness, and loss of bladder or bowel control, requiring emergency surgical decompression.
