Has my implant ruptured again? I am 9 months post op after implant replacement

I had breast implant removal and replacement 9 months ago as my 6 year old implant had ruptured. Last week, I started having similar pains to before (some breast throbbing, shoulder pain, slight numb arm). Been checked by my surgeon who said no signs of capsular contractor or fluid around implant. I asked if it could have ruptured again and he was certain it wouldn’t have at just 9 months after the op. What could be causing this discomfort?
