Aloha,
I'm currently having issue with this movement. (Left Arm)
When I'm on my way down and start to rotate my arm, my shoulder starts to make small popping sounds and struggles a bit to turn. I can still complete the full range of motion but it is not as smooth as it should be compared to my Right Arm. The next the it was pretty sore and tender, my right side is perfectly fine. My range of motion in my left shoulder is a bit of an issue as well but it is not terrible.
Many years ago I had injured it at a military school and has never really been the same since. I have had it it looked at by a few doctors (MRI, X-Ray) and all have said that its fine, it was probably my posture that was creating the issues. One Physical Therapist said I might have a slight rotator cuff tear (stage 1) and was prescribed some shoulder workouts to strengthen the area and roll my shoulder back a bit to fix my posture.
I can still do this movement but rotating the arm for now is a no go.
Should I avoid this movement?
Should I go back to strengthening the shoulder?
Is this normal and just part of the process to getting back shoulder mobility?
BTW I'm a 28yo Army Infantrymen with 11 years of service and my body has been abused a little bit due to the military, working out, and jiu jitsu.
Thanks in advanced!
