Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems like
allergic reaction as the symptoms of red lines or rashes and burning ears along with itching are all pointing towards allergic reaction..
As it is happening commonly after bathing it can be due to any soap, shampoo or other things like detergents used during bathing..
I would suggest you to consult an Allergist and get evaluated and he can do
a thorough clinical evaluation and also advise you allergic tests like
Patch test, RAST test and food challenge test to rule out the exact cause of allergic reaction..
Avoiding exposure to allergen can prevent
allergy symptoms.
You can also be given an
Immunotherapy to reduce the allergy symptoms..
As of now when she gets the reaction she can take anti-allergics like
Allegra or Levocetrizine for relief..
Hope this information helps..
Thanks and regards.
