hi, I have a cold that has been going on for 3 days now. it only gets worse, experiencing very uneasy stomach (no vomiting), head aches, sore throat making it hard to breathe, full body pain and difficulty moving about the house. my final symptom is yellow stool, very bright. throughout the days I tried drinking lots and lots of water, gargling saltwater, drinking lemon water, Gatorade, eating oatmeal and soups. i have never felt this weak and sick before, and i forgot to mention my exterior often sweats while my inside suffers large amounts of cold with heavy chills... what could be wrong with me if I have these stools?
