What is the first symptom in the progression of an epidural abscess after neuraxial block?

• A. Localized back pain
• B. Nerve root or radicular pain
• C. Motor and sensory deficits
• D. Paraplegia

Answer: (A)

Early localized back pain at the site of the neuraxial block is the first signal of an epidural abscess. This initial pain reflects irritation and inflammation within the epidural space as the infection starts. As the abscess grows, it begins to press on nearby nerve roots, producing radicular or nerve-root–type pain that follows a dermatomal pattern. If the infection continues to progress, neural compression worsens, leading to motor and sensory deficits, and ultimately to paraplegia if the spinal cord or cauda equina becomes severely affected. Recognizing back pain early is crucial because it precedes the more serious neurological signs and prompts urgent imaging and treatment.
