I'm not sure if I should be alarmed or not... When completing certain exercises I can hear really light crunching sounds like someone is squishing rice-krispies inside my joints. I have had something like this in my knees for years, and while I hear it doing squats I also hear it going up stairs and have for a long time so it doesn't bother me. It recently started in my left shoulder during push-ups though.
No pain or restricted mobility as a result (that I can tell). Anyone know what cause this? Should I be worried?
Thanks!
