Clicking in arm (think it's elbow)

[30yearlayoff]

My teaching pro started me focusing on proper release and where to generate club head speed (hip to hip).

Since that time, I have noticed a clicking/popping in my left arm (seems to be around the elbow but could be in the shoulder...can tell for sure) when I stretch the arm out and pronate the wrist. There is no paina associated with this clicking. Just concerned it may be leading to something more serious.

Anyone else experience this????
