Two and a Half Thousand Loaded Grips a Shift. Here’s What That Does to Your Hands.
Hand and wrist pain in warehouse work is usually carpal tunnel (night numbness), trigger finger from scanner triggers and carton hooks, De Quervain’s, or tennis and golfer’s elbow. Caught early, overuse settles in 2 to 6 weeks with changes to how you carry and grip, often on modified duties. Established tendon or nerve problems usually take 6 to 12 weeks. Most people keep working through it.
Warehouse work is measured in picks per hour, and that number is the whole story.
A picker doing three hundred picks an hour is doing two and a half thousand loaded grips in a shift, each one a lift, a carry and a place. Nobody would program that as training, and it runs five days a week.
The trouble is the warning signs look small. Stiff fingers at the start of a shift. Numb hands at 3am that shake out by breakfast. A finger that clicks on the scanner.
Ignore those for a few months and the stiff finger locks, the numbness stops shaking out, and you’re the one explaining to a supervisor why your grip gave out with a carton at shoulder height.
So here’s what the tasks do, which problem you likely have, what to change, and how long it takes to settle or get back to full duties.
Why do warehouse workers get hand and wrist pain?
- Picking and placing. Repeated grip and lift, frequently at awkward heights: overhead or at floor level, both of which bend the wrist.
- Box handling. Fingers hooked under a carton edge is a pinch grip carrying a heavy load. This is the position that causes most finger and hand problems in the trade.
- Scanning. One finger on a trigger, thousands of times, usually the same finger.
- Pallet trucks and cages. Push and pull force through the hands with the wrist in whatever angle the handle dictates.
- Wrapping and taping. Repeated rotation under tension.
- Cold stores. Same load, stiffer tissue, less sensation, harder gripping.
(Building a mixed pallet is basically Tetris, except the blocks weigh as much as a toddler and nobody gets a high score for good wrist position.)
Picks per hour is a hand metric. Everyone treats it as a productivity one.
Which one do you have?
Where it hurts tells you most of the story.
- Night numbness in thumb, index and middle: carpal tunnel syndrome.
- Catching at the base of a finger, worst in the morning: trigger finger, the classic scanner-trigger and carton-hook injury.
- Thumb-side wrist pain lifting with the thumb up: De Quervain’s.
- Inner or outer elbow pain: golfer’s elbow or tennis elbow.
- Little-finger-side wrist pain on rotation or when pushing a cage: TFCC injury.
- Numbness in ring and little fingers: cubital tunnel.
- Aching across the hands that builds through a shift: general overuse.
Acute injuries too: a finger caught between a carton and a shelf edge is a crush injury, and rings plus moving equipment are how ring avulsion injuries happen. Take rings off for the shift.
How is it diagnosed?
Mostly with hands-on tests. Scans come in for injuries and for problems that don’t settle.
- Tinel’s and Phalen’s tests: tapping over the carpal tunnel, or holding the wrist bent, to see whether your numbness reproduces. Nerve conduction studies if it’s constant or surgery is being discussed.
- Feeling for a nodule at the base of the finger that catches as the finger moves: trigger finger.
- Finkelstein’s test: thumb tucked into a fist, wrist tipped toward the little finger. Sharp thumb-side pain points to De Quervain’s.
- Resisted wrist movements: pain at the outer or inner elbow points to tennis or golfer’s elbow.
- Grip strength, both hands: a drop on one side is a number you and your employer can both track.
- X-ray after any crush or fall, cos a fracture changes the whole plan.
How long does it take to settle?
Typical ranges once the carrying and gripping change. Change nothing and the clock doesn’t really start.
- General overuse (aching that’s gone by next morning): 2 to 6 weeks, usually without time off.
- Trigger finger: a splint for 6 to 10 weeks settles many. If it keeps catching, a steroid injection or a quick release.
- Carpal tunnel: a night splint trial of 6 to 12 weeks while the numbness still comes and goes.
- De Quervain’s: 6 to 12 weeks with a thumb splint and load changes. Injection if it hasn’t shifted by about 6 weeks.
- Tennis or golfer’s elbow: 3 to 6 months, sometimes longer.
- Broken finger from a crush: 6 to 12 weeks to heal, with at least 6 to 8 weeks protected. Fingertip tenderness can hang around for a few months.
The nerve problems run on a window. While numbness comes and goes, it’s OPEN: splints and load changes often work, and surgery works reliably if you need it. Once numbness is constant, it’s CLOSING. Once the muscle at the base of the thumb has visibly wasted, the goal changes: surgery still stops it getting worse, but feeling and strength may not fully come back. That’s why a numb hand is the one to report early, not the one to tough out.
What actually changes it?
- Carry boxes with flat hands underneath, not fingers hooked over the top edge. Single biggest change available.
- Use handholds and box cutouts where they exist, and ask for them where they don’t.
- Gloves that fit. Too tight costs force on every grip across a whole shift.
- Alternate the scanning hand and the trigger finger where the system allows. A ring or wrist-mounted scanner spreads the load differently; ask if it’s an option.
- Keep loads between knee and shoulder height when you have a choice about which face of the pallet to work.
- Rotate tasks. Pick, then pack, then replenish, rather than eight hours of one.
- Warm hands in cold stores, with liners and warm-up time.
Which splint, and when do I wear it?
- Trigger finger: a small splint holding the knuckle at the base of the finger straight, at night and on lighter tasks, for 6 to 10 weeks. See trigger finger splint and exercises.
- Carpal tunnel: a straight-wrist night splint every night for 6 to 12 weeks. Not cocked back.
- De Quervain’s: a forearm-based thumb splint at night and outside work for 3 to 6 weeks. Some people can wear it on lighter duties.
- Wrist sprain or TFCC flare: a wrist support for heavy tasks in the first few weeks, then weaned off.
What exercises help?
Short and often. Pain no more than about 3 out of 10, and back to baseline by the next morning.
- Pre-shift warm-up: 10 slow full fists and 10 wrist circles each way, longer in cold stores.
- Tendon glides: straight hand, hook fist, full fist, flat fist. 10 rounds, 3 times a day. Good for trigger finger and carpal tunnel.
- Median nerve glides: 5 slow, gentle reps, 2 to 3 times a day if you get numbness. Stop if the tingling builds and lingers.
- Wrist extensor isometrics for elbow pain: press the back of the hand up into your other hand, wrist straight, 30 to 45 seconds, 5 times, once or twice a day.
- Then slow wrist curls with a 1 to 2 kilo (2 to 4 pound) weight, 3 sets of 15, once a day, lowering slowly. Elbow tendons usually need 6 to 12 weeks of this.
Can I keep working, and when can I go back to full duties?
Most overuse problems are managed at work, with modified duties for 2 to 4 weeks: lighter picks, fewer heavy cartons, task rotation. A good rule: if it’s back to baseline by next morning, the load is okay.
After surgery or injury, these are typical ranges. Your surgeon’s protocol wins.
- Carpal tunnel release: light duties around 1 to 2 weeks, light picking around 3 to 4 weeks, heavy lifting and pallet work often 6 to 8 weeks or more. Palm tenderness under pressure can last up to 3 months. See carpal tunnel release recovery.
- Trigger finger release: light duties around 2 weeks, heavy gripping about 4 to 6 weeks.
- Broken finger: light, protected duties may be possible early with your surgeon’s say-so. Heavy cartons usually 8 to 12 weeks.
- Crushed fingertip: light duties with a fingertip protector in 1 to 2 weeks for many, full gripping when the tip tolerates pressure.
These are reportable work-related conditions in most jurisdictions, and a record made early is worth more than one made after you go off sick. Returning to work after a hand injury frames the conversation around specific tasks rather than a blanket fit-or-unfit verdict.

What does a hand therapist do differently?
- Name the problem precisely, because a trigger finger and a nerve problem need different fixes.
- Fit a splint that works with gloves and a scanner, not one that comes off by first break.
- Write task-level advice your supervisor can use: which picks, what weight, which hand, for how many weeks.
- Build a strengthening program that gets you back to full rate, then progress it.
Get it checked today if
- Any crush injury to a fingertip, including one that seems minor, especially with a cut nail bed or a bent finger.
- A ring injury, or a finger that’s cold, white or numb after getting caught.
- A finger that’s red, hot, swollen and throbbing after a cut or splinter.
- Sudden loss of grip or a visible deformity after a fall or a dropped load.
Get it checked if
- Numbness that has stopped coming and going.
- A finger that catches, locks or will not fully straighten.
- Grip failing before the end of a shift.
- Pain present at the start of a shift rather than building.
- Six weeks of changed carrying, gloves and task rotation with no improvement.
The rate is set by the system. How you hold the box is set by you.

This article explains; it doesn’t examine. Numb hands at night or a finger that catches on the scanner are worth reporting and assessing now, while the fix is still simple.
