Shoulder Press Clicking

[conscentity]

Hi all! It's been a while since I last posted. Lately, as I have been going to the gym, I've noticed that both my shoulders click when doing shoulder presses:

It happens on the way down when I return to the starting position. There is a click and a slight hint of pain in both shoulders.

I have been trying to strengthen my internal shoulder muscles by doing external and internal rotations:

But I haven't been at it long enough to really, notice if that helps with the clicking.

Any of you have this happen? If so, have you found anything that helps?
