YOU SHOULD READ THIS POSTING WITH YOUR PARENT(S) OR LEGAL GUARDIAN.
To qualify myself, I am not qualified to coach or to evaluate youth athletics. I have no education in that specific field, nor have I ever desired to acquire the skills to involve myself in youth baseball.
However, in my travels I have experienced just enough. through observations, common language crossovers, and such, to familiarize myself with just enough to hold my own in simple conversations, and related things. Sport's injury, common and across the board with respect to language and related topic are some of those related things that I alluded to earlier.
In the field of athletics, we're very specific with respect to the language of injuries. In that regard, where injuries are concerned, we are very concerned with descriptive language. Take for instance the language used to describe a "minor" sprain compared to a "compound" fracture.
The reasons for telling you this is because I'm concerned with your description of your injury - as you described it... a torn growth plate.
Again, I am not qualified to evaluate youth injuries and related matters. However, as I understand it, growth plate injuries are graded in degrees of "fractures," not tears and the like. I could be totally wrong here.
So, if you're re-wording your injury.. in other words different than what you were told, there's a problem here trying to offer suggestions (suggestions ONLY) and the collective advice to help you. I'm also concerned with a throwing program after damaging a growth plate, regardless how small.
A very good friend of mine has a son that played very competitive hockey. Here in Western Massachusetts hockey is very much part of the nap-n-weave of everyday life for many. Any way, his son was playing in a 14 age bracket and got checked pretty hard, went down on the ice and fractured his right elbow. After a period of medical attention and non-play, he returned to the ice and after a few slap shots he's right-handed, off the ice he came. The young man is now in his early 30's and has some kind of restrictions in his right arm ... arthritis or something like that.
These injuries that you and others experience have long ranging impacts with your quality of life as you get older. So, look to the long ranging influences on your way of life with this injury that you have now and how you take care of your body.... this body is the only one you're going to be issued , so make it last.
