How do I know what causes hay fever in my child?

Doctor's Answers 2

Yes, it is definitely worth having an allergy test to identify the triggers of your daughter’s hayfever. Not only can you then learn to avoid the triggers once they are known, but there are now also newer forms of treatment for certain triggers such as grass and house dust mite which aim for a permanent cure to desensitise the immune response against these triggers.

Some of my child patients also suffer from asthma and eczema, conditions which are well known to be associated with hay fever or allergic rhinitis. So finding out what triggers are causing flare-ups of their health problems is extremely useful not only to me as the ENT specialist but also to their skin and chest doctors too!

Allergy tests may be done as skin prick tests (see picture below) or running an allergy panel in the form of a blood test. I think that each test is equally sensitive but it is important to stop all anti-allergy medication such as antihistamines (e.g. telfast, clarityn, zyrtec) 48 hours before undergoing the allergy test, otherwise, the results may come back as falsely negative.

Skin prick tests usually test for an average of 8-10 triggers whilst the blood test is able to screen for up to 46 different potential triggers.

Hay fever is commonly due to allergies. These allergies can be tested for with either skin prick test, dermal patch test or blood tests. Consult your Paediatrician or ENT specialist about these tests.

Why am I getting clear, yellowish discharge from my ears?

Thank you for your question. From the symptoms that you described, you may be suffering from an ear infection. The two most common ear infections are: 1. Otitis externa – infection of the ear canal 2. Otitis media – infection of the space behind the ear drum You will need to see a general practitioner or ENT Specialist to have the infection treated. Since you have been getting an ear discharge, you will most likely need antibiotic ear drops.

When should I take antibiotics for a cold that’s not getting better?

The common cold is a viral infection of your upper respiratory tract (includes the nose, sinuses and throat). There are over 200 viruses that can cause a cold and an adult may on average experience a cold two to three times a year. Young children (especially those less than 6 years old) are most at risk of getting a cold.
