Steven,
When doing your daily press-ups, make sure you DON"T go deeper than your upper arm parallel with the floor. I mean, don't let your elbow come past your ribs. This places to much stress on the joint!
This is why I was asking about your board type. Usually when we "pop up," it is a sudden, all forces go movement from a DEEP stretched shoulder position. This is just stretching your shoulder out more. This would be easier to modify on a longboard, but play around with techniques on your boards.
Do you have full range of motion in that shoulder compared to the other side?
Exercises:
Start with some multidirectional isometrics...
If you have more pain, stop or do less!
With these, start easy, see how your body reacts and increase workload accordingly. Start with 1 set, at 50% effort and so on...
Keep me in the loop with what your feeling after the workouts...
External rotation: Stand next to a door frame, elbow bent at 90 degrees and a rolled up towel up under your arm pit and palm of your hand facing midline of your body. Press your fist into the frame as your try to externally rotate your arm. Hold for 6 seconds, 3 sets of 15 reps.
Internal rotation: Stand next to a door frame, elbow bent at 90 degrees and a rolled up towel up under your arm pit and palm of your hand fcaing midline of your body. Press your fist into the frame as your try to internally rotate your arm. Hold for 6 seconds, 3 sets of 15 reps.
Adduction: With a pillow between your chest and your arm, squeeze the pillow with your arms. Hold 6 seconds, 3 sets of 15.
Flexion: Stand facing a wall with your elbow bent at a right angle and held close to your body. Keep your elbow near your ribs, not in front and not behind or out to the side. Press your fist forward against the wall. Hold 6 seconds, 3 sets of 15.
Extension: Standing facing away from the wall with your elbow bent at a right angle and touching the wall. Keep your elbow near your ribs, not in front and not behind or out to the side. Press the back of your elbow into the wall. Hold 6 seconds, 3 sets of 15.
Abduction: Standing with your injured side towards the wall and your elbow bent at a 90-degree angle. Press the side of your arm into the wall as if attempting to lift it. Hold 6 seconds, 3 sets of 15.
Depression: Sit in a firm chair. With arms at your side, press down on the chair seat and lift your butt up. This is much harder and maybee too advanced... Hold 6 seconds, 3 sets of 15.
Work up to the sets and reps as your body acclimates to the activities without pain!
Once you master (pain free sets and reps completion, during and after) these, I will advance you.
