hey, i found out from the doctor 7 days ago that i had glandular fever, and i'm still ill as anything, i know it can take 2 weeks to go away but the lump on my neck isnt going down, and whenever im sick, cough, hiccup, yawn ... i get this intense pain in the space between my ribs under my chestbone, what is it? Paracetamol doesnt help the pain at all
