Hi Rachelle, I had my op there too, you are in good hands!
your pre op is straight forward. They will take your height, weight, bloods etc and discuss any medications you are on etc....
I am sure your neurosurgeon has discussed the operation with you....
As for things to take in.....
lots of loose fitting pj's, nighties etc. I had button up ones as they are easier to change out of.
slippers, dressing gown, standard toiletries, lip balm, squash and your favourite tasty snacks. You will feel and probably will be quite sick afterwards, so you won't want to eat a great deal, but if and when you can, do try.
The meds will make you constipated, fact! So, take some decent laxatives with you or ask for some, you don't want to be straining! Trust me.....
you may like to read a book or magazine? I couldn't for a few weeks. But I did have music on my phone which helped to distract me from general noise on the ward.
My best advice is to be positive, do not over do it, rest and definitely do your neck exercises as soon as you can. As for your hair, don't worry about that, it will soon grow back and you can show off your scar to your friends!
Can I help with anything else?
