I had a breast augmentation done through my armpit using mentor smooth saline 375 cc placed under my muscle about 2 years ago. When I try to use my chest muscles for normal everyday things or even just raising my arms the muscles will shake/jump uncontrollably and tremor. If I flex the muscle as hard as I can then the shaking stops, but causes cramping so I don't like to do it. Is this a normal outcome and risk from a breast augmentation?
