Is it dangerous for me to under go a rhinoplasty and breast augmentation at the same time if i'm under weight? is the pain recovery quite tolerable?

Cosmetic surgery: It is not unheard of to undergo multiple procedures on the same setting. Be sure your surgeon is board certified with expertise in these procedures.

Possible: It is possible to do multiple cosmetic surgeries but keep in mind that each requires time, a great deal of effort on the surgeon's behalf and artistry. You do not want the surgeries to be rushed for the sake of getting two done on the same day. www.artofplasticsurgery.com

It's ok: The combination of those two procedures should be fine. Prophylactic antibiotics should be administered and the pain level should be tolerable.
