Thanks for providing more information.
Sorry for late reply and inconvenience.
Well as you are suffering from last few years and based on your recent MRI, you have degenerative arthritic changes of the shoulder joint.
SLAP tear refers to the torn cartilage over the ball of the arm bone attached to the shoulder joint.
Besides that, the rotator cuff muscles supraspinatus also has been damaged.
This type of problem requires surgical intervention for proper repair and improve your range of motion at shoulder joint and elbow.
Cortisone injections can be tried before considering surgery.
I understand your concern regarding opting for surgery however it's essential to consider a proper treatment as if you leave it untreated then it can cause complete loss of movement and disability.
So make an appointment with your Orthopedist in next few days for further evaluation and management.
I hope this helps.
