I have had more trouble with my shoulder since surgery then I had before surgery, with the scar tissue and something not healing correctly and now arthritis that is why my neck surgeon will not touch me after two neck surgeries remember, you are young and things can happen later on and also get a second and possibly a third opinion if possible you might want to use it a little so your shoulder will not freeze up on you, I am no Dr. But I am speaking from experience plus being a caregiver, heck. I have even taken care of dr's. (they are the worse patients I have ever taken care of). You might even talk to a naturopathic Dr. I hope I have helped!
Sincerely,
sandy
