Hey MsLizzy,
Sorry you are here, I hope we can help you. There have been many firefighters that have passed through here. You can find them by searching, e.g. "firefighter" or for docs, "San Fransisco."
You ask some tough questions that really address the quality of life issues for all of us patients. If you are properly indicated for surgery, and you have a good, experienced surgeon, you should be able to recover and return to work. But firefighting is tough work! Please do reach out to the other firefighters, EMTs, et al from this community and talk to them -- that's why this community is here!
