Thanks for your query.
Symptoms of your daughter are suggesting pinworm infestation.
Since you have already given deworming medicine,it should not persist.
I suggest you to give a course of albendazole
and repeat it after 15 days.
Maintain proper hygiene,trim her nails regularly.frequent hand washing should be done.wash fruit and vegetable with plenty of water.
Avoid fried and junk foods(chocolates do not cause worm infestation.)
Give her plenty of fluids,salads.green vegetables.She should not be constipated.
Wishing your child good health.
