Which direction, not which spot.

Because most low back pain is non-specific — no single structure can be identified as the cause — so pointing at the sore spot doesn't give a precise answer. What is genuinely useful is which direction of movement eases it: some backs prefer bending forward and dislike arching, others the reverse. That distinction changes what you should do and what to leave alone for now, and it's something you can test yourself over a few days.

Not the main one, and it's worth being straight about that. The strongest and most consistent evidence for ordinary back pain is for staying active, avoiding bed rest and gradually rebuilding tolerance to movement. Stretching supports that and doesn't replace it — which is why the routine includes gentle strength work even though it's less appealing. The other common trap: reflexively stretching hamstrings by bending forward, which for a bending-intolerant back makes things worse.

Numbness around the genitals, buttocks or inner thighs, new difficulty passing urine or controlling your bladder or bowels, or weakness in both legs. That can indicate cauda equina syndrome, where delay causes permanent bladder, bowel and sexual dysfunction — hours matter, and it means an emergency department rather than a routine appointment. Progressive leg weakness, fever with back pain, unexplained weight loss or a cancer history also need assessing rather than exercising through.

Possibly not. Disc bulges and degenerative changes are extremely common in people with no back pain whatsoever, so imaging frequently finds things unrelated to the actual problem. That's why guidelines discourage routine scans for ordinary back pain — the findings can make people more fearful and less active, which makes the pain worse rather than better. Ordinary back pain generally improves, and that isn't a dismissal of how much it hurts.

Follow a plan you wrote before the flare, because six in the morning is a bad time to decide anything. Reduce load rather than stopping entirely, keep moving gently and often, and use the direction that eases it. Prolonged bed rest makes ordinary back pain worse. And one thing worth holding onto: with ordinary back pain, hurting more doesn't mean more damage — those two come apart, and knowing it changes how people behave in a flare.
