After doing a delt workout using bands during the day, I woke up the next day and my right shoulder is in trouble. I have pain more towards the front, and when I lift my arm horizontal and twist there a good amount of popping and cracking. I've slept funny on my left shoulder about 4 years ago giving my tendonitis (spelling), and not being into lifting didn't really need to do anything other than rest according to my doctor. (The NHS are great

But now, I'm looking for information on shoulder health, and after reading 'The Foundations of Shoulder Health' topic picked up a few stretches;
Band Pull-Aparts Behind The Neck
Band Pull-Aparts
My workout targets all 3 deltoid 'heads', and incorporate the rota cuff when a can, doing external rotations.
I've seen 'LYTP' mentioned a few times but have no idea what it is really? I also have no idea how/if you can use a tennis ball for soft tissue regarding the delts? I'm only a beginner and looking forward into discovering more but for the moment, I only really need easy-to-understand stuff, as the shoulder joint is stupidly complicated
