y dad s been sick for about 24 hours now. It seems to be either a bad stomach virus or kidney stones. Lots of vomiting, no headache, some lower back, pelvis, and stomach pain. Hasn t been able to sue the bathroom so not sure about blood in urine or stool. Has a history of kidney stones in the family, and the areas in pain seem to follow in accordance with that, but the amount of vomiting seems strange. He says the nausea comes and goes. He s hydrated. I make sure he keeps drinking water, but as soon as he drinks it he gets nauseous and starts to vomit. Hasn t eaten in 24 hours now and didn t sleep more than few hours last night.
