The conditions of back ache, back pain, and lumbago are typically classified as either acute, when symptoms are felt for a short-period time, or chronic, meaning sufferers are affected for an extended period.

Back ache, back pain, and lumbago are conditions that can manifest as either a dull ache or a sudden, sharp pain. Other symptoms can include muscle spasms, soreness, and difficulty in walking.

Back pain affects a significant proportion of adults worldwide. Possible causes of back pain include ligament or muscle strain resulting from injury or repetitive movements, ruptured or bulging disks leading to nerve compression, arthritis causing spinal stenosis, osteoporosis involving compression fractures in the vertebrae, and skeletal irregularities.

These conditions are often associated with occupation-related factors, such as jobs that involve heavy lifting and bending or sedentary jobs, like office-based work.
