Internal scarring - is there treatment for this?

I had breast implants removed in 2008 and peri areolar lift, following complications from previous surgery. My chest muscle was over dissected & the implants were touching. I had reconstructive surgery to correct/reattach muscle. In 2015 I had another successful augmentation with peri areolar lift. My issue now is there is an indentation under my left nipple along the original incision scar. I am assuming the internal scar has hardened causing a pinched area. Is there treatment for this?
