this might seem really thick to be asking this, but how long is a cough supposed to go on before it is some sort of lung infection or whatever?? had very bad sore throat 6 weeks ago and better but if get sonething more than liquid in throat that tickles a little (very hot Tesco's Salsa) am almost coughing up tonsils and nearly throwing up (sorry to be graphic) not that bad but there have been incidences where I have just avoided coughing at work and swallowed as too embarassed to be making so much noise (seems like a fuss over nothing I know but have never had a cough like it and coughing isn't normal coughing) if anyobe has any experience of any sorts I'd be extremely grateful to hear from you thanks Lavenderxxx
