Hi Magzy01...first of, don't worry! We have all seen some pretty bad shoulders...at your age, i do not think yours would be beyond repair (that is an uneducated opinion though ! )

In fact, we have all seen shoulders that have a full thickness tear and biceps tendon damage which do well without surgery...it depends on what you plan to do with your shoulder.

Your body is very good at dealing with pain - in all likelihood, you won't have this pain this bad forever...a bit of hard work, some rehab, perhaps surgery if required and you will likely have a functional shoulder again.
