I believe to have a rotator cuff tear( currently deployed cannot see a professional). why is one shoulder lower and how can i correct it? thank you

Cuff strengthening: Try your best to maintain a full range of shoulder motion. With your arm bent at a right angle (90 degrees) raise your arms upward from your side. Have a friend provide some resistance to raising your arm too. Rotator cuff tear is not present if no pain with resistance. Pain with resistance may be either an inflamed rotator cuff, partial thickness tear or small full tear. Phys therapy if possible.

Muscle imbalances.: You may have muscle imbalances that can be corrected with physical therapy.
