I once kept my contact lenses overnight (more than 24 h all in all) and got an eye ulcer it hurt so much I couldn't walk my mother had to ask for a wheelchair at the hospital.
Also a kidney infection - it was a mild one, but still. The full blown kidney thing is a killer, my brother in law had a calculus once and when the pain kicked in it was so overwhelming he had a seizure on the spot. It's like the brain disconnects itself because it can't handle the pain, said the doctors.
