OH Press Pain w/ DB but not BB

Just wondering what this might be. Everyone seems to always say the BB OH causes them pain, but in my case my right shoulder has alot of discomfort with DB OH presses.

Thinking is has something to do with the width of my grip/elbow spread, I’ve tried wide grip BB OH presses as well…with no discomfort. * scratches head*

No other shoulder exercises (laterals, upright rows, etc) bother it. What gives?

When in the ROM does it hurt and where in the shoulder?

Hard to describe where in the shoulder, just seems like radiating discomfort. Not sharp just not “normal”

Mostly the bottom half ROM.

Cant replicate the sensation with light weights (<45) either.

Video shot from the front, back, side (both sides).

And don’t purposely use textbook form just because you are being filmed. Do the movement as you normally would.

Also, a brief history of your lifting/athletic background.
