I've had my implants for 3 1/2 months under muscle. I just started going back to the gym and after the last time, I'm pretty sure I over did it. I mean I didn't lift more than 40 lbs and I did it on machines, but the next morning I woke up and my whole body was sore from pushing it too far. My shoulder/ neck was sore like it was pulled. When I got out the shower I noticed in the mirror that my right breast was higher than the left. I called ps, he said to take it easy and take muscle relaxer
