What could be causing my son's body itching without a rash, stomach pain, increased appetite, and white spots in his stool, even though he was dewormed last month and is currently taking an antihistamine, and what medicines can I give him for his stomach pain and itching since a similar episode last year was treated with Banocide syrup and an antihistamine?
The white spots in his stool, itching, stomach pain, and increased appetite suggest a persistent or new parasitic infection, like pinworms, which can sometimes recur even after recent deworming. Since he was previously helped by Banocide (diethylcarbamazine), it is best to consult his pediatrician before restarting it. A simple stool test can identify the exact parasite to ensure correct treatment. For now, you can continue his prescribed antihistamine to help soothe the itching, but please consult his doctor before giving any new medications for stomach pain.
