My left hand when rotated clockwise always cracks like it's rolling off another joint. Any other direction of movement hurts. What condition is this, why does it happen, and how do I repair?

it really depends on if you have recently had an injury to that hand or possibly over extended it doing an activity that you normally don't do. if there is no known injury you may want to have it checked out by your primary care doctor there's numerous different reasons that would cause the symptoms that you have listed and without more evaluation it would be hard to pinpoint the 3xact cause or how to repair or remedy this problem. more information would be highly appreciated and recommended.

true. these things define the personality of the person.
