I do them inbetween Arnold Dumbbell Press and Upright Barbell Rows. I guess I'll make a new workout for shoulders. And I looked up some proper form videos on youtube and I can clearly see how shitty my form has been. I've simply been straightening my arm when I should bend it slightly.
Nope, I don't have pain doing any other exercises and this was the first day I've had pain while doing them aswell. There is a popping sound sometimes but that's normal, right? It happens in all joints and is because of gas bubbles or something I read.
If this is the first time they've been hurting, it may be buildup from bad form or just you went too heavy and tried to force your way through the reps. *shrug*
Popping is fine. Long as there's no pain afaik.
A lot of exercises are outdated and there's almost always better alternatives (even if you do have damage you can do something similar that helps you "heal"), make sure you do research on everything you do or you might wake up one day with permanent damage, take care guys.
Personally I was doing bar dips improperly and my shoulders hurt for a good while even in a rested position, still kind of hurts really, don't be me. 
Dips are one of those exercises that you can do them or you can't. Some people just can't do them even if their form is right on. They'll get injured regardless. Just seems that way from what I've heard and seen from other people and myself.
But some of the exercises that will never be outdated are squats, deadlifts, pullups and overhead presses. Just can't beat them. Not the end all be all but if you only did those 4, you're in good hands. It'd be better to have some other ones to balance things out like rows ofc but dam those 4 are juicy. Fuck the bench press. I may suck at it but still.. fuck it.
