Replying to It's Official...TORN MEDIAL MENISCUS

ok-i posted a thread about my knee injury a couple days ago and i got an mri today: torn medial meniscus. i go to surgery thursday...but heres the thing-they said depending on how big the tear is, i could be down for a little as 24hrs, or up to 6weeks! now, im no doctor but i really dont think that after surgery on something like a knee will only put me out for 24hrs...if any of you have nething that may help calm me down before thursday, id appreciate it!
