Hi im 23 and right now my symptoms are nausea, chills, fluctuating BP (130/97 87 my last take) some abdomen discomfort and heartburn. Please help?

Call your doctor. this sounds like a gastroenteritis, but could be also sign of serious problem. Do not eat, drink plenty of fluids, prefer pedialyte or gatoraid. If unable to keep fluid down, vomiting blood or black, having black stool or low blood pressure, seek immediate help.
