From 3 hours ago I have extreme abdominal cramping and nausea. Now I feel cold whilst I am covered. Have had a cold for about a week. What is this?

See below. Symptoms suggest gastroenteritis (inflammation of stomach and intestines)most often due to one of several viruses and occasionally due to food poisoning. Ginger Tea or Ginger Ale may help the nausea. OTC pain medication like ibuprofen,Advil, Aleve, (naproxen) aspirin WON'T help this type of pain. If the symptoms don't improve soon or get worse need to see Dr for a precise diagnosis and specific treatment.
