Nipples permanently erect after over 1 and half years since surgery?

I had my breasts enlargd from AA with 260cc implants in 09/2014. I am happy with the job, but there are a few things that bother me. They haven't "dropped" and altho they are soft they still look too high up on my chest. also, my nipples are always erect. I have to wear bras all the time because they stand out through my clothing. Will my breasts drop and my nipples go back to normal to get a more natural look? I trust my doctor but we are in different countries and he just says it take time.
