Take some time off from lifting and let the inflammation settle down. Tendons are slow to respond, so give it plenty of time. During this period, do your rotator exercises to strengthen the cuff and gentle manual stretching to improve your range of motion, especially if you have some impingement going on in your shoulders. As lifters bulk up, impingement can be a big problem. The can cause tendons to be irritated. Fish oil and NSAIDS can be helpful too.
Then when you get back, examine your lifts to see if you are doing anything to aggravate that area. A PT once explained to me that any shoulder lifts you can do with your palms facing up rotates the shoulder cuff so it has more room to work in there. That would be a good thing.
Good luck bro, it can be a very stubborn problem.
