Hi I am 21 years old. I have never had a shoulder injury or anything and I have no pain in my shoulders. However I have no external rotation in my shoulders for some reason but every other ROM is fine and normal.
My GP said think that I was born like this and it will never improve I just have to deal with this.
Is this true that it will never improve or should I work hard on flexibility and would it improve or should I not bother??
