My sister's had a cough for the last few days.. and now, for some reason, my throat is really itchy.. along with my jaw a little bit. it's itchy at the base of my throat.. and sometimes now when I turn my head it makes me cough... and my head hurts... I wonder if I'm coming down with her cough.. the urge to cough is stronger if I press on my chest...like right under my throat...I keep panicking that I'm like having a heart attack or something but that's really irrational :/ I'm 18.. but my parents keep telling me if I keep up with my bad eating habits I'll get one :/ I probably am just getting her cough, or have allergies or something... are my symptoms normal for just a cough (she's had a slight fever too, I don't feel like I have one)? I don't want to have a cough... but I can deal with it. should I eat dinner? Or would that make things worse? does this sound like a sv? thanks
