Im 13 years old and I've been suffering from symptoms of a cold for as long as I can remember. My nose is constantly blocked, I'm always sneezing and have a runny nose. I'm really getting sick of it. Also, most mornings I wake up with a sore stomach and mucous in my throat. sometimes i vomit up water too. i dont eat breakfast because I can't stomach food and then my school work suffers because I cant focus on anything but the pain in my stomach. Please help me!
