I never really thought that I could actually injure my shoulder while playing badminton. Yes, I know my smashes are insane killers and would scare almost all of my opponents but I never really saw it as powerful as they did. Not to mention, now that I'm no longer training in my high school varsity, I consider myself very out of shape - that includes my smashes.
It's not as strong as it used to be but it still serves it's purpose.
Unfortunately, I stretched too much and I think I pulled a muscle and compressed a nerve. So, now, I'm taking a vacation from playing and wait until it heals before I resume.
I tried playing with the sore arm. I can't smash so I banked on all the other moves. Unfortunately, the injury has also affected the other moves so I decided to hang the racket up for a while.
It sucks but I think it'll only take a while. I can already move it freely so it won't be long. I'm trying to stage the great return. :)
