Most likely it is your connective tissues that click over other tissues as you move your joints. It is benign unless there is pain associated with the movement. Over time , if left untreated, it can become more chronic and fibrous and build up more thickness. This tends to pull your tissues tighter and may cause more pain and restrictions in range of motion, which is usually due to old injuries or even longstanding poor posture. Better to have these conditions checked early in childhood to prevent a chronic problem later in life... even later ... spinal adjustments and tissue therapy help like "taking a foot off a garden hose" to increase circulation and speed healing time. Have that "Clicking" checked today!
