Back pain: what actually works (and what's a posture myth)

What has strong evidence

1. Keep moving. Strict bed rest makes acute low back pain worse. Walk; do what you can tolerate.
2. Strength training. It's the best-supported treatment for chronic low back pain: planks, bird-dogs, hip thrusts, rows and, progressively, a well-coached deadlift. A strong spine is a brave spine.
3. Sleep and stress. Chronic pain is amplified by bad nights and constant tension. The nervous system modulates pain — take care of it.
4. Losing the fear of movement. Kinesiophobia (fear of moving) predicts chronification. Pain education reduces disability.

What's smoke

Back braces for daily life, "miracle" mattresses, obsessive posture-correcting and MRI scans for every ache — herniations and degeneration show up on scans of people with NO pain at all. Treating the scan instead of the person is a trap.

Red flags — see a doctor now

Pain after significant trauma, loss of strength or sensation in the legs, fever, loss of bladder or bowel control, night pain that won't ease, or unexplained weight loss. In those cases, investigation is urgent — no lone heroics.
