My Name Is Karen, I Have A Lap Band, But

My name is Karen, I have a lap band, but I've never experienced restrictions with any foods except cornbread. I had the lap band adjusted 5 times and I finally gave up. Should I get it removed? I injured my Left shoulder-had rotor cuff tear surgery, I also injured my left lower back and legs. The automated doors closed on me at work. I've had a hard time trying to find any exercise that won't hurt my shoulder, back and legs. I've recently started doing aquatic PT, which seems to be helping. Are there any exercises you can recommend I do outside of the pool that won't agitate my injuries? I'd like to have the sleeve surgery, I was told the lap band has to be removed before the sleeve surgery can be done.
