Rowing is the sport that most reliably produces one specific and frequently misdiagnosed injury: pain a hand’s width above the wrist on the back of the forearm, sometimes with a creaking you can feel through your fingers.
That is intersection syndrome, and rowers get it more than almost anyone else.
It gets treated as De Quervain’s, because they sit close together, and the treatment differs.
Why rowing does this
Feathering the blade rolls the wrist repeatedly, thousands of times per session, while the hands grip the handle under load.
Two tendon groups cross over each other in the forearm and rub at that crossing point. Add cold, wet conditions and a jump in training volume, and the picture is complete.
- Feather with the fingers, not the wrist. The commonest technical cause, and coachable
- Loosen the grip on the recovery. Most rowers hold the handle as hard on the way forward as on the drive
- Check blade pitch and rigging. A blade that is hard to feather forces the wrist to do it
- Build volume gradually, particularly at the start of a season or after a break. Nearly every case follows a step change
If you can feel a creak under your fingers when you move the wrist, that is not a strain. It has a name and it responds to changing the feather.
The rest of it
- Thumb-side wrist pain, lower down: De Quervain’s, which needs a thumb spica rather than a wrist brace
- Inner elbow pain from sustained gripping: golfer’s elbow, with its own loading programme
- Forearms that pump and fail at the same point every piece: exertional forearm pain
- Numbness in the fingers on long pieces: a nerve, worth reading the pattern rather than dismissing
Blisters and hands
Blisters are part of the sport and mostly harmless. What matters is the small number that stop being skin problems:
- Keep them clean and covered. A torn blister on a boathouse handle is an open wound in a wet, shared environment
- A blister that becomes increasingly red, hot and painful over a day or two is infected, not healing. Hand infections run on hours — see cellulitis
- A whole finger swollen evenly, held slightly bent, agony to straighten: that is a flexor tendon sheath infection and it goes to hospital tonight. Rare, and the one that costs fingers
- Do not pop and ignore. Trim flat, dress, cover for training
What to do if it has started
- Change the feather first. Technique before treatment, because the treatment fails without it
- Reduce volume for two weeks genuinely, not nominally. Erg work spares the feathering action and keeps fitness
- Relative rest, not immobilization. Keep the wrist moving through comfortable range
- Six weeks of changed technique and reduced volume is a fair trial. No change means it needs assessing, and intersection syndrome that has not settled often responds well to an injection
Get it assessed if
- Swelling or a palpable creak that is not settling
- Pain present before you get in the boat
- Numbness in any fingers
- A blister getting redder rather than better
- Six weeks with no improvement despite real changes
Dragon boat, kayaking and canoeing produce a similar picture through a similar mechanism — repeated loaded wrist movement in a fixed grip — and the same technical fixes apply.
Rowers do not get a mysterious forearm problem. They get a specific one with a name, and it starts at the feather.
