I have some questions about bunion surgery?!

I have some questions about bunion surgery?

Its the weekend and my docter is out, so I thought I would ask you guys.
How long is the surgery itself? I also have to get a cyst out too, so how much time do you think that will add to the procedure?
Were you able to walk normally after 3-4 weeks? I have an engagment 3-4 weeks after my surgery and it requires walking a couple miles.
Thanks

the surgery lasts long enough to remove the bunion ,not more then 1/2 an hour=an hour tops for both=you should be able to walk in 3 weeks =take care not to harm it or will be longer in healing
