Breast/nipple/sometimes armpit pinches, stings, pains

You did not state what size implants you have. If they are large, they may be too large for your frame and tissue. Otherwise, you might have some capsule formation. Go back and let your surgeon check you.

It’s unusual for patients to have breast pain after breast augmentation.
However, lots of women have intermittent breast pain whether they’ve had surgery or not.
It’s unlikely your breast pain is related to how the surgery was performed.
Many women have breast pain without having an understood or underlying ideology.
There’s a fair amount of information about breast pain available online or you can talk to your primary care provider.
