I have been feeling sick for 3 weeks now (nausia, dizzy, headache, tired, stomach pains). what do i do?

See your doctor: Your symptoms remind me of a viral infection, but most acute viral infections last no more than 10 days. With these symptoms, you should definitely see your physician, who will probably get blood tests, and perhaps imaging tests such as ultrasound or ct scan.

Preg test, see GP: You are describing non specific symptoms which often turn out to be a viral illness. If so, the symptoms will resolve within a week. If not consider pregnancy. Try ginger ale, getting good nights sleep, eat small amount five times daily, avoid alcohol or spicy foods. If your symptoms persist, what you do is get ye to a gp-:). (if you can find one.).
