how to ask my surgeon for extra time off?

at my pre-op appointment my surgeon said that most guys only end up taking 4 weeks off of work. but my job requires me to walk and lift lots of gadgets; anywhere from 10-45lbs. i don’t know if just didn’t fully understood what my job requires of me or if i would really be okay after 4 weeks.

maybe i could make it work? idk, it makes me kind of nervous though, i basically work in retail during the holiday. it would make me feel better to have around 6 weeks off and just start work again in the new year.

has anyone else able to ask for a little longer time on leave? i have to email them with the paperwork soon and i’m having trouble figuring out how to ask :(
