Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that due to a large number of
insect bites there has been
allergic reaction to the toxic chemical injected by the insects under his skin leading to swelling and itching..
But as he does not have any systemic symptoms like
dizziness, breathlessness etc you need not to worry as there does not seems to be excessive concentration of toxins in his blood and he will gradually recover from the swelling and itching too..
You should continue applying Advantan cream that is a steroid formulation and will help in reducing inflammation, swelling and itching..
Claritin that is an anti allergic should also be continued..
You can also apply
Calamine lotion to reduce irritation..
You can also do cool compresses over the swellings..
Hope this information helps..
Thanks and regards.
