An isolation gown so your arms are protected. An apron cannot protect your arms.
Headaches and getting hungry :P
Well, you have two options, either throw up now and not worry about it later (this relieves pain too), otherwise, just drink something and have something to eat. Don't try anything too sugary like one of those Starbucks unicorn drinks (I don't know if they still exist but hey, just a warning!). Try a soda or just plain water. For something to eat, try a corndog or something that you like. Most people like pizza, so try a nice greasy pizza!
