I replied to your post on the ENT board and recommended you come on this board too.
Your dr may be putting you out for many reasons, he may be doing the surgery by laser, mine used a drill (!) and then yelled in the operated ear to ensure I could hear him before sticking all th packing in..
As far as I have read some people have NO vertigo and some have lots its a crap shoot I guess, from others post here I think everyone responds differently to the surgery...some have pain but no vertigo, some nothing and some pain, dizzies and numb stuff...I just wished I had been on this board before instead of after so I could have been better informed
My dr advised very little of anything for 7 days including panicing (!)
PLease dont; worry you may be fine afterwards
I did feel great on day 2 went to the mall, out for lunch and then paid for it the days after.
I think if you relax for the 5 days you have booked off you will be fine.
