Planning... I think an unexpected drug side effect is important enough to warrant not waiting for your doc... he should have someone "on call" to cover for him while he is on vacation.
Just someone to talk to to confirm what is happening, that it is OK to stop taking the Zyprexa suddenly, and mostly to put your mind at ease, maybe he/she can answer your question about how fast this should go away. Maybe even suggest something to help the swelling go down more quickly.
My feet ankles and knees really swell when my arthritis is bad so I know how bad and scary that can be... sometimes not even being able to put on socks, let alone shoes. Hope you can get an answer from someone, even if it is only temporary until your regular doc gets back.
