Breast reduction ????

Hello I’m 19 wear a size 38 D bra my upper back starting to hurt but I haven’t really been paying it no mind because it could been because I pick up boxes that’s heavy because I stock at work which probably cause me to strain my back muscles but do you think a 38 D is to big for sumone that weigh 120 my weigh goes up and down

But I was wondering for the teens that have had beast reduction how was it ? Why did you get one ? How did you tell you doctor about you back problems?

TMI : Here are sum pics of my chest
