Shoulder Pain

Hey guys, not sure how I hurt it but I did, the pain is in my side delt and I feel it when I do DB Flyes, and chest pressing movements…for the last 3 weeks i have been doing a lot of rotary cuff excercises to warm up with and then just DB raises from different angles, basically anyone else have this happen to them and is it tendinits?

My shoulders have improved oddly enough by doing all the side shoulder movements
