Hello! i m in excellent physical shape. i ve been exercising for many years. recently my joints started to click, what? is it trouble? but no pain!

Not necessarily: Clicking of joints with out pan may not be a big problem . THe cause may be due to sudden movement , may be displacement of vacuum in cavitation ) , adhesions in side the joint , or rarely due to lack of enough lubricating fluid in side the joint ( synovial fluid ) These don't have t be concerned only time to worry is if there is injury to joint ligaments , cartilages , meniscus injuries etc
