Can Costochondritis cause complications during surgery?

Thanks for your inquiry, it is hard to predict, but two weeks is a long time.  An above the muscle implant I expect would have less concern then an under the muscle given your diagnosis, good luck.  

Most cases of costochondritis have no apparent cause. In these cases, treatment focuses on easing your pain while you wait for costochondritis to resolve on its own. Symptoms of costochondritis should not cause implications during BA, but be sure to inform your board certified plastic surgeon of your past history with flareups during chest workouts. 

Thank you for your question.If the implants are being placed subglandular, this should not have anything to do with the pain you are already experiencing. Breast augmentation above the muscle is a pretty quick recovery, with minimal discomfort.
