2 weeks post op. 300cc over muscle saline implants. Doing well. Small bruise Should I be worried? (photos)

You don’t say if the bruise is new but bruising is common after surgery and your body may still be flushing away blood from where cells were damaged at the site of the incision. If the bruising is new, you may want to ask your plastic surgeon at your next follow-up appointment. As for the sunburn feeling, a burning or tingling sensation can be a good sign after breast augmentation because it means your nerves are regenerating. Breast augmentation can stretch your nerves, causing them to send out intermittent "shocks" after surgery to reconnect with your tissue, which could be the burning you’re feeling. The sensation should ease in the next few months as your body recovers.

This all looks fineTake things easy and adhere to post-op instructions by your surgeonGood luck!

Thank you for your question and photos.  This more than likely represents post-operative healing.  Contact your surgeon for further information.  Good luck.
