possible rotator cuff injury

[Guest ilove2workout28]

I don't know how I did it, but I think my rotator cuff is slightly injured. I think it was either pushing the full back lever (my new record today was 10 secs, then did it again for 5 secs), but it may have been Bulgarian dips, 10 reps, but slow, and I paused at the bottom position for 2-3 secs for each rep. any thoughts? The pain is on my right shoulder, the part connecting to the clavicle.
