Hi, Thanks for using the HCM.
Your childs symptom suggests either allergic condition or viral infection, if this type of symptoms are recurring again and again, its more suggestive of allergic condition. start some first aid
like, warm salt water gargling, steam inhalation, to prevent further bacterial infection and she can be started with safe antihistamics, but dosage depends on her weight , she also needs mild anti inflammatory agents. so consult/call your pediatrician
for further management .No need to worry for present condition .
Hope I have answered your query. If you have any further questions I will be happy to help. Thanks get well soon....
