Will breast become soft again after firm and hard seroma found by MRI scan?

Had over the muscle silicone breast implants removed 9 weeks ago with minimal capsule removal as i have little breast tissue.. fluid build-up was suspected early on but surgeon suggested leaving it to go away on its own. About 5 weeks post, my right breast started to get hard and firm towards the back of the breast. MRI scan identified fluid build-up overlying the pectoralis muscle and seroma within the implant cavity.. what should be my next step? or will my get breast go soft again on its own?
