I am just entering 8 weeks post breast implant surgery (submuscular) and i think i felt something sting inside my left breast as i positioned my arm to reach for a bed lamp switch while i kept my torso on its back unmoved. i didn't engage the torso to avoid using my right side as I reached for the bed lamp. my arm was a little over 90/angle. it wasn't a strain, didn't hurt ...Am I imagining this?
