Craft injuries are almost always a dose problem, and the dose spikes in a very particular way: someone finishes a project over a long weekend, or takes up a new craft in January, and does in three days what their hands would normally do in three months. The hobby did not cause it. The step change did.
Which is good news, because a dose problem is fixable without giving up the craft.
What each craft loads
- Knitting. Sustained light grip plus repetitive wrist and finger movement. Thumb-heavy in some styles. Continental style loads the left index finger; English style loads the right wrist and thumb
- Crochet. More thumb and pinch than knitting, because the hook is held in a pinch grip and the tension hand pinches the yarn. The commonest craft source of thumb base pain
- Hand sewing and embroidery. Fine pinch, sustained, often with the neck and shoulder braced
- Quilting and machine sewing. Repeated pushing and guiding, plus rotary cutter work, which loads the thumb hard
- Cross stitch. Long static holds rather than repetition. Different load, same outcome
What turns up
- Thumb-side wrist pain, worst lifting with the thumb up: De Quervain’s tenosynovitis
- Grinding at the base of the thumb on jars and keys: thumb base arthritis, which the craft aggravates rather than causes
- Night numbness in the thumb, index and middle fingers: carpal tunnel syndrome
- Knobbly, aching end joints: finger osteoarthritis. Crafting does not cause it, and being able to keep crafting depends on managing it
- Catching at the base of a finger: trigger finger
- General aching that builds through an evening and settles overnight: overuse, and the most likely answer
Nobody knits themselves into an injury at two hours a week. They do it at twenty hours in one week, in December.
The changes that let you keep going
- Twenty minutes on, two minutes off. Hands open, arms down, fingers straight. The single most effective change, and the one most people will not do because they are mid-row
- Thicker handles and hooks. Ergonomic crochet hooks with a wide grip, or foam tubing over a thin hook, genuinely reduce pinch force
- Larger needles and looser tension during a flare. Tight tension is a grip problem in disguise
- Change project type rather than stopping. Alternating a fine project with a chunky one varies the load
- Support the work. A cushion under the forearms means the shoulders and wrists are not holding position for an hour
- Rotary cutters with a soft grip, sharp blades, and a ruler with a handle
If it already hurts
- Two weeks of genuinely reduced volume, not “a bit less”. This is the diagnostic test as much as the treatment
- Full finger and wrist range daily, gently, morning and evening
- A thumb spica splint at night if the pain is at the thumb side of the wrist — it must include the thumb
- Warmth before a session, not after
Get it assessed if
- Numbness that wakes you, or that no longer comes and goes
- A finger catching, locking, or not fully straightening
- Pain that is there before you pick the work up
- Six weeks of real reduction with no change
- Morning stiffness in both hands lasting more than an hour — that is a different question, covered in stiff, swollen fingers in the morning
If you also spend the day at a keyboard, the loads add up across the whole day rather than resetting when you get home: hand and wrist pain from desk work.
Your hands do not know it is a hobby. They only know the hours.
