Good Morning, My Child Drank Paraffin Yesterday, But She Swallowed

Good morning,

my child drank paraffin yesterday, but she swallowed a little and started coughing. we gave her 2 glasses of milk, and rushed her to a nearby hospital where they gave her charcoal, within 2 hours she started being her usual self. In the morning she complained about her stomach being painful, is this anything to worry about? she is 7 years old.

regards,
keke
