Hi my 5 year old son has very congested the past week, I think it is due to high pollen.I have tried saline nasal spray to try and relieve congestion. However in the last few days he has had a nose bleed in the morning and then twice today.. he also had few spots on his bum the last few days nowhere else just his bum. What should I do.
Hello and welcome to Ask A Doctor.  I have read your query and here is my advice.  He may have nasal allergies. Nose bleeds can be caused by allergy.  Other signs of allergy include a personal or family history of hay fever, asthma, and eczema.  Does your son also have cough, a fast respiratory rate, or his neck muscles pulling when taking a breath?  These can be indications that he is working hard to breathe and are seen in respiratory infections below the nose, for example
