Wrist Pain on the Pinky Side? Here's What It Means and What to Do
Updated July 20261 minute read
Pain on the pinky (ulnar) side of the wrist often involves the TFCC — the cushion-and-ligament structure there — especially with twisting (doorknobs, jar lids), gripping, or pushing through the hand. It can also follow a fall. It's usually manageable with relative rest, splinting, and progressive strengthening. Significant pain or instability after a fall, or numbness, needs evaluation.
What this usually means
Most likely causes. A TFCC injury is the classic cause of pinky-side wrist pain, often provoked by twisting and weight-bearing. A wrist sprain can also localize here. Less common causes. Tendon irritation on that side or, after a fall, a bony injury can contribute.
What you can try at home
Reduce twisting and pushing through the hand temporarily, keep the wrist neutral when loading it, and consider a supportive wrist brace short-term. Gentle wrist and forearm strengthening builds tolerance once it settles.
When to see a physical therapist
If pinky-side wrist pain persists or flares with twisting and loading, a PT can identify the cause and build a plan.
Red flags — don't wait
Seek prompt care for significant pain and instability after a fall, deformity, locking, or numbness/cold fingers.
How a PT treats this
Treatment offloads the area, then progressively strengthens the wrist and forearm and grades return to twisting and weight-bearing.
