Do you know how to stop my symptoms i have vomiting and face rash and upset stomach. and i want some answers on it?

See a doctor: You ask how to stop your symptoms. There are medicines that can decrease vomiting, but it's really more important to find the cause and treat it rather than your symptoms. You need someone to do a good physical exam and possibly order some tests to diagnose and treat you properly. It's not possible to do this over the internet. There are many possible causes. Good luck!
