Today , my son had 2 mini Fizzer's and almost immediately after he started coughing a lot.

He has had some chest and coughing problems and it's almost a regular thing , but this was so striking that immediately after having the sweets , he started exactly the same kind of cough.

Could he be allergic to any of the ingredients inside the sweets and how do I get him tested for the certain ingrediants etc ?

Will my GP know what to do ?

So clueless , but want to help my boy urgently.

Thanks
