I had implants, placed under the muscle about a year ago (500cc right and 550cc left). I love the overall look of my right breast but the left one has always felt a bit "off" and has muscle distortion when I flex. Recently, I noticed if I put inward pressure on my left breast, in the lower cleavage area, I feel an electrical shock sensation that runs through to my nipple. I know nerve damage can result from surgery but I am over a year post op and just now noticing this. Should I be concerned?
