Cracking your knuckles causes swelling in the hands.

the verdict
INSUFFICIENT LEANING
Recorded sources
2 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that cracking your knuckles causes swelling in the hands?

Unclear. One 1990 observational study of 300 patients reports that habitual knuckle crackers were more likely to have hand swelling and lower grip strength, but it is a single correlational study and does not establish that cracking causes swelling. Other retrieved items concern arthritis, joint mechanics, or unrelated topics and do not address hand swelling.
