This section explains the common back and neck conditions people search for, from low back pain and neck pain to sciatica, disc bulges and herniations, stenosis and scoliosis. Each article covers what the condition is, how it is recognised, what usually happens over time and which treatments have evidence. Most back and neck pain has no single identifiable cause and is not dangerous, and many findings on scans are common in people without pain, so the articles separate what a diagnosis means from what a scan report says. Every condition page lists the warning signs that need a doctor, and links to the practical guides on exercise, staying active and pain relief that help most people recover.
