I was snowboarding and I landed on my right shoulder.  I stretched out my ligaments in my right shoulder that hold the glenrolhumeral joint in place.  My subscapularis muscle and acromiocoracoid ligament were also damaged.  i tried many things to fix this problem such as chiropractor, acupuncture and physiology therapy.  Nothing worked until I found Prolotherapy.  I have been doing Prolotherapy for 5 months now and have seen great results.  It feels much stronger now.
