I get it too. Mine is on the inside of the elbow (not sure if it's tennis or golfer elbow), but like BC said, you cannot flare your elbows out. I get discomfort on any incline presses or overhead movements if my form is not strict. Dumbbells may work for you because you can change the angle to more of a neutral grip and see if that helps you out any. I have taken extended breaks throughout the years, and it has never gone away, so I kind of just put up with it.
