Ok so at a high level then. If you want to stay there get this shoulder injury treated properly so you can stay there for the long term. This is the second time it has impacted on an important fight from what you say, you really need to get this sorted or it will keep coming back and as TM says it will just get worse as you get older. You are young and it may not be what you want to hear but if you take a few months out to fix this shoulder properly when you are young it will help you later if you want to make a career out of fighting or any atheletic pursuite. And if you are as good as you say you are that (your ability) wont change and you will only get better once this injury is fixed.
