Answer:
A feeling of painless joint "popping" is not terribly worrisome and can be normal for an individual. In major joints like the hip, knee or shoulder, an increase in popping can be a sign of weakness in the surrounding musculature, and well-directed strengthening could help stabilize and maintain the health of the joint.
If the "popping" is painful, or has a grinding element to it, that could signify loose tissue in the joint and should be evaluated by a physician.
