Choked voice and cough along with fever
suggest that your kid most probably has a throat infection
I can be viral or bacterial. Its better that you have him examined by a pediatrician
. If the doctor feels findings are suggestive of a bacterial infection, he might advise antibiotics.
And regarding crocin
, appropriate dose should be given in appropriate intervals. Usual dosage is 15mg per kg per dose given four times a day.
Since your son`s weight is on the higher side, he needs correct dosage.
You can ask him to go gargling with warm salt water if he can do it.
Since he has a stomach ache too, I would suggest you to get him examined by a doctor than self medications. Usually in viral illnesses, kids develop gastritis
, in which pain is felt in upper abdomen, and he will be okay if treated for that.
Wish a speedy recovery for your son.
