Welcome in H.C.M.
I have gone through your query regarding sore throat
and abdominal problems of your 6 years old daughter. After considering the the symptoms it appears as your daughter is suffering from viral fever
This is a very common presentation of viral fever in children
You may give these to your child-
1- Tab Paracetamol
2- Antacid with domperidon.
3- Warm saline gargling.
I hope this will help her otherwise thorough examination by paediatrition will become necessary.
