I'm getting a pectus excavatum corrective surgery/how risky? How badly will it hurt?

Ask Surgeon. Discussing those questions with your surgeon is part of your informed consent. Ask your surgeon.
It all depends. Generally, this is not a high risk operation but that also depends on the experience of your surgeon and the overall quality of your institution. There is pain involved but it can be adequately managed with an epidural or pca and/or oral pain pills. Usually the pain service is consulted for pain management.

Depends... Everyone's pain tolerance is different. You will either have a nuss procedure that involves incisions on your sides and likely chest tubes after surgery. The other is the ravitch procedure that would involve resection of the cartilage of some of the ribs and direct implanting of a bar. This typically does not have any chest tubes left behind, though it can have more pain than the nuss repair. Read more...
