Back Conditions & Diseases
Medical conditions affecting the back area or system
Low Back Pain (Non-specific)
MildCommon discomfort in the lumbar region without a clearly identifiable cause.
- Dull ache in the lower back
- Stiffness after rest
- Pain worsened by bending or lifting
Herniated Disc
ModerateDisplacement of nucleus pulposus through the annulus fibrosus, compressing nearby nerves.
- Sharp pain radiating down the leg (sciatica)
- Numbness or tingling in the foot
- Muscle weakness
Lumbar Spinal Stenosis
ModerateNarrowing of the spinal canal in the lumbar region, leading to nerve compression.
- Leg pain or cramping when walking
- Numbness in the feet
- Weakness in the lower extremities
Degenerative Disc Disease
MildAge‑related wear and tear of intervertebral discs causing loss of disc height and flexibility.
- Chronic low‑back ache
- Pain that worsens with prolonged standing
- Occasional leg pain
Sciatica
ModeratePain that follows the path of the sciatic nerve, usually caused by nerve root irritation.
- Burning pain down the back of the thigh into the calf
- Numbness in the foot
- Muscle weakness in the leg
Spondylolisthesis
VariableForward slippage of one vertebra over the one below it, often in the lumbar spine.
- Lower‑back pain
- Stiffness
- Radiating leg pain
Ankylosing Spondylitis
VariableChronic inflammatory disease that primarily affects the sacroiliac joints and spine, leading to fusion.
- Persistent lower‑back pain
- Morning stiffness lasting >30 minutes
- Reduced spinal flexibility
Osteoarthritis of the Spine
MildDegenerative joint disease affecting facet joints and vertebral bodies.
- Dull aching back pain
- Stiffness after inactivity
- Pain worsens with extension
Facet Joint Syndrome
MildPain arising from inflammation or arthrosis of the facet (zygapophysial) joints.
- Localized back pain that worsens with twisting
- Radiating pain to the buttocks
- Stiffness
Lumbar Strain
MildOverstretching or tearing of muscles or ligaments in the lower back.
- Sudden onset of back pain after lifting
- Muscle spasm
- Tenderness to touch
Cauda Equina Syndrome
SevereMedical emergency caused by compression of the nerve roots at the end of the spinal cord.
- Severe low‑back pain
- Loss of bladder or bowel control
- Saddle anesthesia
Spinal Tumor (Benign)
VariableNon‑cancerous growth within or adjacent to the spinal canal that can compress neural structures.
- Gradual back pain
- Radiating nerve pain
- Numbness or tingling
Spinal Metastasis
SevereCancerous spread to the vertebrae, often causing structural compromise and pain.
- Persistent, worsening back pain
- Night pain
- Neurological deficits
Vertebral Compression Fracture
ModerateCollapse of a vertebral body, frequently due to osteoporosis or trauma.
- Sudden sharp back pain
- Height loss
- Kyphotic posture
Osteoporotic Vertebral Fracture
ModerateFracture of a spinal vertebra caused by reduced bone density.
- Mid‑back pain
- Tenderness over the fracture site
- Limited spinal flexion
Discitis
SevereInflammation and infection of an intervertebral disc, often bacterial.
- Severe back pain
- Fever
- Elevated inflammatory markers
Epidural Abscess
SevereCollection of pus in the epidural space that can compress the spinal cord.
- Back pain
- Fever
- Neurological deficits
Spinal Meningitis
SevereInflammation of the meninges surrounding the spinal cord, usually infectious.
- Intense back pain
- Fever
- Neck stiffness
Cervical Myelopathy
VariableCompression of the spinal cord in the neck region leading to neurological impairment.
- Neck pain
- Hand numbness
- Gait instability
Cervical Radiculopathy
ModerateNerve root irritation in the cervical spine causing pain radiating to the shoulder and arm.
- Neck pain
- Radiating arm pain
- Numbness in fingers
Thoracic Spinal Stenosis
VariableNarrowing of the spinal canal in the thoracic region, less common than lumbar stenosis.
- Mid‑back pain
- Radiating chest or abdominal pain
- Numbness in the legs
Kyphosis
MildExcessive forward curvature of the thoracic spine, often postural or due to vertebral collapse.
- Rounded upper back
- Back stiffness
- Mild pain
Lordosis
MildExaggerated inward curvature of the lumbar spine, sometimes causing discomfort.
- Prominent lower back curve
- Lower‑back ache
- Muscle fatigue
Scoliosis
VariableLateral curvature of the spine that can affect the back muscles and posture.
- Uneven shoulders or hips
- Back pain
- Limited flexibility
Spinal Osteomyelitis
SevereInfection of the vertebral bone, often secondary to bacteremia.
- Persistent back pain
- Fever
- Night sweats
Facet Joint Arthropathy
MildDegenerative changes in the facet joints leading to inflammation and pain.
- Localized back pain
- Pain worsens with extension
- Radiating pain to buttocks
Lumbar Disc Degeneration with Radiculopathy
ModerateDegenerative disc changes that compress a lumbar nerve root, causing radicular symptoms.
- Low‑back pain
- Leg pain following a dermatome
- Numbness in the foot
Post‑Traumatic Back Syndrome
VariableChronic back pain and stiffness following a spinal injury without obvious structural damage.
- Diffuse back ache
- Muscle tightness
- Reduced range of motion
Spinal Cord Injury (Incomplete)
SeverePartial damage to the spinal cord resulting in motor and sensory deficits below the injury level.
- Back pain at injury site
- Partial loss of sensation
- Weakness in legs
When to Seek Medical Help
For back conditions, consult a healthcare provider if you experience:
- Persistent or worsening symptoms
- Sudden onset of severe symptoms
- Symptoms that interfere with daily activities
- Signs of infection (fever, swelling, redness)
- Unexplained changes or new symptoms
