Low Back Pain

Pain & Nociception
Degeneration on a scan is neither necessary nor sufficient for back pain: disc degeneration and bulges are extremely common in people with no symptoms, and whether the nervous system is turning pain up or down does not show on imaging. So major guidelines do not recommend routine imaging for ordinary back pain without red-flag symptoms; first-line care is a clear explanation and staying active.
Shoulder Pain
Modern care for acute soft-tissue injuries has replaced complete rest with appropriate loading: long bed rest or keeping an arm in a sling both weaken the muscles that should stabilize the joint and stiffen the tissues that should glide, so recovery ends up slower.

READ THE ORIGINAL

The lower back is not one bone. It is a structure that has to carry the body's weight and still bend and turn: the vertebrae in front bear the load, a disc sits between them as a cushion, small joints at the back steer the direction of movement, the muscles and fascia alongside the spine act as living cables, and nerves leave through an opening at each level and run all the way down the legs.

The center of a healthy disc has almost no nerves, so seeing degeneration on a scan does not mean the source of the pain has been found. But nerves can sometimes grow into a degenerated disc, so a scan has to be read together with the symptoms. The back is built to bend, twist and carry — it is not a glass rod that cracks at a touch — and most back pain gets clearly better within a few weeks.

Only one situation cannot wait. If back pain comes with numbness around the groin and buttocks as if anesthetized, sudden inability to pass urine or loss of bladder or bowel control, or both legs getting steadily weaker, go to the emergency department now. The full list of reasons to see a doctor is in the chapter on when you must see one.
