Hi and welcome to the Chiari forum.
May I ask what symptoms u present with currently...do u have a CSF obstruction? Why does the dr feel u need this surgery at this time?
The reason I ask, is bcuz not all with chiari need surgery, and if u r as active as u say, u may not be as affected by the chiari....
Everyone is diff but since u r physically fit and if u do have an obstruction and do need to restore flow, I understand having surgery...but it does come with risks and there is no way to say how long, but ur being active and fit can help u in ur recovery.
That said, it is possible to feel worse post op....and benefits should out weight the risks in choosing do have this surgery. U may feel ok at 6 weeks, u may not...outward signs may appear u r healing like ur stitches/scar...but it is the inside and the nerves that can take up to 2 yrs to heal completely....the more u do post op, may cause u to have set backs....
No one can tell u b4 surgery if and when u can go back to sports...u have to wait and see.
Same with the time off school....having the right dr is key!!! Not knowing where u live I will include the dr list for the states....we do have others, but none of the lists r meant as referrals u do need to research all drs.
