First off CC sharl, saw ur other post in my thread and agree il do some more stability work.

I didn realise that a coach was responsible for your injury! And your right it was a national coach here tried to teach me something and i kept doing exactly as he said and when i tried it one day in sparring it dislocated!
(Recently i have discovered how to do the technique correctly and found that he was showing me the completely wrong way. He had obviously just seen it done and said "i'm a boxing trainer i can teach that.")

I really hope you can get some really good treatment for your back after the nationals, its a horrible area to injure and you should definitely look after it!
