Vomiting diarrhea lightheadedness and pretty bad stomach pain. only been a couple if hours. should i see a dr or tough it out and keep hydrated?

Dizziness and more: If you can't hold down liquids, are now dizzy, ; you have what sounds like significant abdominal pain you should really be evaluated by a physician without delay. At the very least you are at risk of dehydration. Self limited distress is not worrisome. But if progressive, persistent, and worsening symptoms then don't try to sit this one out!
