Have any of you guys encounter this? This has been going on for quite sometime but I never really paid that much attention to it. Basically, whenever I start doing shoulder presses with a dumbell, on both of my shoulders (mainly left), I would hear a click/pop/snap sound. I would press the dumbell up and and SNAP..lower it..push up..SNAP...

My description sucks but I'm pretty sure some people would get what I'm trying to describe. What you guys recommend me to do? Is this a normal problem or should I go see a doctor about this?

Thanks in advance
