Thanks for query
your son has food poisoning. I think you had already been given proper antibiotics in the proper doses. Now he is having rashes with itching in his body. It indicates that he is having allergic manifestation to that food or to the drugs given. Now it will be wise to start anti-histaminics in the form of cetrizine, desloratdine or fexofenadine along with if not controlled then dexamethasone injection is to be given. Probably by all thses your son will get rid of this episode. But for future you should consult an allergist to detect the culprit allergens by allergic skin prick test or specific serum IgE test and specific immunotherapy against them will give your son some sort of protection on further exposure to those allergens.
Thank you.

Allergist and Immunologist Dr. Sujoy Khan's  Response
Urticaria secondary to infection is a common occurence.
I hope the bug that caused the food poisoing illness has now been identified and treated.
Urticaria can be treated succesfully with long acting antihistamines like Allegra but needs to be taken for 6 weeks after an infection.
Non-sedating antihistamines (like Allegra) is better than sedating ones as he is already exhausted.
Please ensure that the entire symptoms of rash, abdominal pain and vomiting are NOT secondary to viral infections such as dengue virus (as it is now quite common in several parts of India).
Dengue IgM test will let you know if currently infected along with NS1 Ag but needs to be done withing 5 days of illness. A CBC with platelet count is also mandatory.

General & Family Physician Dr. Mian Sohaib Khalid's  Response
While hives are generally harmless most of the time, they can be very harmful and can cause your child to experience difficulty try with over-the-counter or prescribed antihistamines drugs and use any Emollients and as antihistamines may fail you may need short course of an oral corticosteroid for 5 to 7 days or a single dose of long acting injectable steroid.
