3 Months Post Breast Augmentation: Experiencing Pain

it's been a week now that i feel localized pain on my left breast(the pain is like a bruise). i feel the pain on the sides of my left nipple toward my left arm. i also feel the pain on the incision site after i wear my none wire bra(like there's a feeling of heaviness),everytime i bend over(this time on the side of the left nipple again but extending medially)& when sleeping on my left side. is this something serious or it's just a sign of drop and fluff? thank you for the replies docs.
