@lucieroyer I’m 2 and a half weeks post op and I have exactly the same sensation in my right arm/breast only my left is perfectly fine . I have a feeling it’s because that’s my dominant arm that I use more for holding and carrying things etc. many girls and the nurse have reassured me it’s perfectly normal and that I just need to wait for my muscles to relax and release their ‘hold’on the implant , I imagine it’s just a case of the muscle being a little tight at the moment xxx
