Any older sci patients out there dealing with partial rotator cuff tear

I have had a partial rotator cuff tear for about 6 months now and was wondering if anyone else has advice on managing the injury. Cotizone shots are out for me as I had a bad reaction when I had one for my injured thumb a few years ago, it sent me weird in the head for some reason and my doctor said I reacted to the steroid component which made me very moody almost aggressive . I am a incomplete T4 38 years post transverse myelitis with chronic neuro pain to add to my joys. I saw a physio once every 2 weeks for treatment and do my rehab exercises at home now as acupuncture didn't do much good

Any older sci patients out there dealing with partial rotator cuff tear
