Why Does My Lower Back Hurt When I Bend Over?

Bending forward loads the muscles, joints and discs of your low back, so if one of them is irritated, bending is often the first thing that hurts. Common causes include a strained muscle, a sensitive disc or stiff joints. Your spine is built to bend, and most bending pain gets better as you keep moving and slowly get used to bending again.

Common reasons bending hurts

  • A strained or tight muscle. Often after lifting, yard work or a long day of bending. The pain is usually achy and stays in the low back.
  • An irritated disc. Discs are the cushions between the bones of the spine. A sensitive disc often hurts with bending forward and sitting, and sometimes sends pain into the buttock or leg.
  • Stiff or irritated joints. Some people feel it most when they straighten back up from a bend, rather than on the way down.
  • Guarding. After a flare, the back muscles can tighten up to protect you, which makes bending feel stiff and sore for a while.

Pain when bending does not mean you are causing damage. Many people have disc changes on scans with no pain at all.

What usually helps

  • Keep bending, just less. Practice gentle bending within a range that feels OK, and slowly go a little further as it eases. Avoiding bending for weeks can make it stiffer and more worrying.
  • Bend your hips and knees for heavy or awkward loads, and keep the load close to your body. Research hasn't found one “correct” way of lifting that prevents back pain, so use what feels strong and comfortable.
  • Stay active. Walking and normal activity are usually better than bed rest.
  • Try heat to ease stiffness before you move.

Most people feel a lot better within a few weeks. If bending still hurts after that, or keeps flaring up, it's worth getting it checked.

When to see a doctor

See a doctor promptly if you have:

  • Numbness in the groin, buttocks or inner thighs, or new trouble controlling your bladder or bowels: get emergency care
  • Weakness in a leg or foot that is getting worse
  • Pain, tingling or numbness spreading below the knee
  • Back pain with fever, unexplained weight loss or a history of cancer
  • Back pain after a fall, or if you have osteoporosis

How physical therapy at ARI can help

A physical therapist can work out which movements bother your back and which ones ease it, then help you rebuild bending and lifting step by step. Exercise to strengthen your back, hips and legs can help you bend with more confidence and fewer flare-ups.
