used constantly for gripping, typing, opening containers, driving, and holding objects, a poorly fitted thumb ring can quickly become uncomfortable.
A good ring should feel secure without squeezing the finger.
How a Thumb Ring Should Fit
The ring should slide over the knuckle with mild resistance and rest comfortably at the base of the thumb.
It should not:
Leave a deep indentation
Cause numbness
Produce tingling
Make the thumb feel cold
Cause swelling below the ring
Turn the skin blue or purple
If any of these changes occur, remove the ring.
