I had 280cc, silicone, under the muscle implants in 2011. On and off (but more on recently), I have had rib pain on both sides that's even tender to touch. Seen the surgeon and he did an ultrasound and said nothing is wrong with the implants. Well in the past 3 years I have had surgery for thoracic outlet syndrome on my right side. I wonder if this could be due to the implants too? The rib pain right now is mostly on the left side right now. No breast dimpling, swelling, firmness, asymmetry.
