Noise is normal. Painful noise could be a cause of concern. As we age, parts of our body naturally break down or degenerate. Also, you could have a minor tear in your labrum or your rotator cuff. Again, this is perfectly fine unless there is terrible pain with it. Over the years, I’ve had diagnoses of a left shoulder labral tear, right shoulder rotator cuff tear and tears in both mensci. These cause no trouble whatsoever other than an occasional noise and do not hinder my workouts.....unless it’s a bad bent press.
