Yesterday I Woke Up With Stomach Pain (burning, Nausea). Throughout

Yesterday I woke up with stomach pain (burning, nausea). Throughout the day I had diarrhea and vomiting, ran a fever (around 100-101), and had a severe headache and body aches, especially in the lower extremities. Today I have a low-grade fever but feel better; however, I have a blotchy red rash on my stomach near the bottom of my rib cage. The blotchy area has grown larger throughout the day. I an a 51-year-old female.
