So what if there is pain as in my case? It's mild muscular pain...surrounding the joints.
Hi.
The joint cracking is actually a benign condition and is thought to be a result of any of several causes. One of these is the accumulation of gases around the joint causing tiny gas bubbles which result in joint cracking when they are released.
Another probable cause are tendons and ligaments crossing over the joints and these may crack as they snap over the joint's bony prominences.
One other cause may be because of arthritis, but is usually found in those who already have an established diagnosis of arthritis, so it would be unlikely in your case, especially with the absence of pain or swelling.
Hope this answers your query.
