<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 3 year old daughter has really smelly snot I took her to the doctors on Friday but to be honest he was hopeless and said it might be a infection , I told him I can see some thing tissue like up her nose he had a look and said its most likely muscus and gave her some piraton . Im not happy still and I dont think that its muscus because I can still see it . I have got her to blow her nose a few times but its not moving to me it looks like its attached to her nose and I dont think its an object or food . Have u any ideas what it may be  <response>: Thanks for asking in Chat Doctor Forum In Short: Foul smelling discharge from one nostril may be a foreign bodyExplanation: In child Chat Doctor. So, foul smelling discharge may be because of this. You have already shown to a doctor, but you are not convinced. So do one thing, visit a ENT specialist who can look it very well through their special instruments and convince you accordingly. Good luck
