I'd go with the itch. In the 1 out of 1 cases I know of where someone had chronic hiccups, they ended up going to jail for murder.
I've had the hiccups for multiple days, it was more than just annoying. I remember it being painful on my clavicles after the first day
The itch would bother me more, but the hiccups would bother other people more. I'm not sure which I would choose.
fuck others if I have to suffer then everyone else can suffer too
edit: figuring out whether or not I'm joking is left as an exercise to the reader
Suicide will be easier with just an itch.
Edit: Wait, no! We have euthanasia here. Hiccups so I can get medical sign-off.
TBF I don't know how serious I actually am about that, we'd see. They both sound like hell though.
The itch would be impossible to prove and I'd just be seen as a grumpy asshole, at least the hiccups can be understood
I get chiggers at my camp about every weekend in the summer, no matter how much bug spray. One itch would be a relief.
