Is it possible to have swelling 6 months post BA op? (Photo)

I am a 30 year old female, 4'11 weighing roughly 130lbs. I was just told by my nurse that I still have some swelling and to wait it out. She sad this can happen if you are petite. I did some realself searching and some docs said that if dropping happened it would have already. What's weird is my right side has this mild pain all the time but not my left. The pain is especially prominent after I workout but only my right side. I'm here looking for second opinions.
