What can be done to correct a fold in my breast implant?

I had breast augmentation 7 years ago (I am 43) and have never had any problems apart from finding a few breast lumps over the years that always came back as benign. I recently had a mammogram and ultrasound for a painful “lump” on my left side that had been on off over the years but lately had become painful. The ultrasound and mammogram came back clear but the MRI shows a fold which may be the cause of the pain. What steps should I take next? Do I need to replace them? Thanks
