The weather where I am has been rain, rain , rain , hot , hot , gloomy, hot, so on... my sister has a cold or sinus infection and I'm wondering if I have that too. It could be the flu because I recently went to a place packed with people , really easy to pick something up. Anyway I have a stuffy nose sometimes runny , my throat did feel scratchy or like clogged but I've been drinking hot drinks to help that. I've been taking cold relief medicine , cool mint flavor and it's making my stomach feel weird , I'm not taking too much! I read all the labels. And after I take it then eat like 20-30 minutes later I have to run to bathroom (not to puke) I'd just like to know if it's something else or just a cold.
