The answer: dirty socks. I'm thinking of this because I'm packing. When G had his first shunt revision, hubby and I didn't pack anything when we went to the appointment. We live about two hours away from the hospital, so I'm not sure what we were thinking. G was admitted and had surgery that afternoon. It was a Monday, and we came home by Wednesday. I was able to survive the underwear, pants, shirt, but the socks were giving me heaves when I had to put them back on in the mornings. I shudder at the memory.
We've been through a few more unexpected surgeries since then, and I bring extra underwear, but I definitely overpack socks.
G has an appointment today for a CT scan. His behavior has changed, and we're thinking shunt. I hope I'm wrong.
