Overview

Back pain is one of the most common musculoskeletal problems and can happen to people of all ages. It means feeling pain or discomfort anywhere along the spine, but most often in the lower back. Muscle strain, ligament injury, disc problems, or changes in the spine that happen over time can all cause back pain. It can be short-lived, lasting a few days to weeks, or long-lasting, lasting several months. Many cases are mild and get better with rest and basic care, but some may be signs of more serious spinal problems. Early evaluation helps find the cause and stop long-term disability.

Symptoms
Back pain can feel like aching, stiffness, or sharp pain in the affected area. Bending, lifting, or sitting for a long time may make the pain worse. Some people have muscle spasms or less flexibility. If nerves are involved, the pain may spread to the hips or legs and be accompanied by weakness, numbness, or tingling. In bad cases, movement and daily tasks may be limited.

Causes
Back pain can happen when you strain your muscles, sit for too long, lift things the wrong way, or have bad posture. In older people, common causes include degenerative changes such as disc wear and tear, arthritis, or spinal stenosis. Obesity, injuries, insufficient exercise, and stress at work all increase the risk. Infections, fractures, or tumors may be the cause, but this is less common.

Diagnosis
A thorough medical history and physical exam to check posture, movement, and nerve function are the first steps in making a diagnosis. X-rays and other imaging tests may show structural problems. When nerve compression, disc problems, or serious underlying causes are suspected, MRI or CT scans are used.

Treatment
The cause and severity determine the treatment. Most cases improve with rest, and painkillers and physical therapy are used to strengthen the back and core muscles. Using heat or cold therapy and fixing your posture can help. Regular exercise and keeping your weight in check lowers the chances of it happening again. If the problem doesn't go away or gets worse, injections or surgery may be options.

The prognosis for back pain is generally positive, as numerous cases resolve within weeks. Early care, good ergonomics, and regular exercise can help keep your spine healthy and functional and stop it from happening again.
