What are possible reasons that my elbow constantly pops?

Elbow Pops: Joints pop and crack and make all types of noises. If not painful, then we rarely worry about these noises. A shift in fluid or air, bone spurs, roughened cartilage or loose bodies (bone or cartilage) can all account for these noises. If these noises are accompanied by pain, loss of motion, weakness or locking of the joint see your family practice doctor, a sports medicine physician, or ortho surg.
