Why Your Lower Back Hurts After Golf — and What Actually Fixes It

Why the golf swing targets the lower back

The golf swing asks the body to rotate fast, repeatedly, in one direction, from a bent-over posture. That is an unusual demand, and the load has to be distributed across the whole system: ankles, hips, thoracic spine (upper back) and shoulders.

The lumbar spine — your lower back — is built mainly for stability. It rotates very little by design. When the joints above and below it rotate well, it does not have to. When they do not, it makes up the difference, over and over, hundreds of times a week if you practise.

That is why lower-back pain is so often really a hip and upper-back problem. The place that hurts is frequently the place compensating, not the place at fault.

The usual culprits

• Restricted hip rotation — especially on the lead side. If the hips cannot clear, the lower back twists to finish the swing.
• A stiff thoracic spine — common in anyone who sits at a desk all week, which describes most golfers in Bangkok. Restriction here forces rotation downward into the lumbar spine.
• Weak or poorly coordinated trunk control — not "weak abs" in the sit-up sense, but an inability to keep the spine stable while the limbs move fast.
• Poor hip hinge — setting up and bending from the waist rather than the hips loads the lower back before the swing even starts.
• Volume spikes — the classic Bangkok pattern: barely playing during the week, then 36 holes plus a range session at the weekend, or a golf trip after months off.

What actually helps

The effective approach is generally to restore rotation where it belongs, build the capacity to control it, then reintroduce speed. In practice that means mobility work for the hips and thoracic spine, anti-rotation and anti-extension trunk work, and gradually loaded rotational strength — in that order.

What tends not to help, despite being the most common response: aggressively stretching the lower back itself. If your lumbar spine is already rotating more than it should, adding mobility there usually makes things worse. The same applies to endless crunches, which train the trunk in a plane the swing does not use.

Warming up properly matters more than most amateurs think. Ten minutes of movement before hitting balls — rotations, hip openers, some gradual swings building to full speed — measurably changes how the first few holes feel, and the first tee is where a lot of back injuries happen.

When to stop self-treating

Stiffness and a dull ache after a round is common and usually responds well to the work above. There are situations where you should get assessed properly first rather than starting a conditioning programme:

• Pain that travels down the leg, or any numbness, tingling or weakness in the leg or foot.
• Sharp pain rather than an ache, particularly if a specific movement reliably triggers it.
• Pain that wakes you at night, or that is present at rest rather than only after golf.
• Anything that has persisted for more than a few weeks without improving.

Getting it looked at in Bangkok

For a medical assessment, the sports-medicine departments at the major hospitals — Samitivej and Bangkok Hospital among them — see golf injuries routinely, and there are good independent physiotherapy clinics across the city. A single assessment session is usually enough to tell you whether you are dealing with a mechanical problem or something that needs proper investigation.

For the conditioning side once you are cleared, look for a coach who screens before prescribing — see our guide to golf fitness in Bangkok for what that involves and which providers do it. We’ll Golf near Phrom Phong is one option that runs golf-specific sessions with a mobility and pain-reduction focus, at the studio or at your condo; Aspire Club on Sukhumvit 23 has in-house rehab staff, which suits cases where the pain is the main issue rather than performance.

Whichever route you take, do not write off back pain after golf as part of the game. It usually means something above or below the lower back is not doing its job.
