Excessive Mucus for 10 Days but no Temperature. Can it be an Infection if there's no raised Temperature? Feeling like I might need antibiotics (appreciate it could be viral in which case antibiotics no good). Have stayed in and been inactive but wondering how long to leave it before making a doctors appointment. Don't get why I haven't got a Temperature yet still coughing up green mucus, anyone else been there done that? Trying to avoid yet another course of oral steroid tabs, but guess that will have to be the next step.
