silicone implant under the muscle with a lift. a month ago i began to feel something up against my chestwall there is slight pain when i move the implant against the chest wall. This is also the same side i sleep on. I have had a ultrasound that came back normal. I have asked for a MRI but my physician will not order it because of the ultrasound results. Is it normal to feel the implant against the chest wall after all this time? Im so afraid ... The implant is soft .. 500cc
