I have a constant cough that wont go away it has been persisting for 3 days now, cant get sleep because when I lay down it gets worse and I cough every 10 seconds. For the past 3 days I have only gotten about 4 - 5 Hours of sleep. Didnt come to school because I had to go to the Doctor. I hope the cough syrup makes it go away because its getting hella annoying.
