Welcome to Healthcare Magic,
Your son developed
allergic reaction and lotion will not help. Right now he need injection with
hydrocortisone or
methylprednisolone, plus antihistamines injection or tablets such a
Benadryl, or chlorfeniramine and IV fluids. Monitor carefully and if you will note difficulty in breathing, changed voice, dizziness, hypotension then you need ASAP bring him to emergency room.
I wish you good luck and speedy recovery,
Hope this helps and I have answered your query. If you have additional queries don’t hesitate to ask.
Best Regards,
Dr.Mihail
