I tweaked my infraspinatus on my right shoulder. I’m good when I’m training, just sometimes at rest, I feel it a bit, but not too painful. I had graston done to it, and am also using some rock tape. What are some good drills on here that would help me expedite the healing process? Thanks for your help in advance, I appreciate it.
Also try putting a lacrosse ball underneath your infraspinatus while lying on your back and bringing your arm through internal rotation with your arm bent at a 90 degree angle. This will help loosen up the upper back muscles like the infraspinatus that are responsible for external rotation.
