Hi.
Thanks for your query.
Noted the history and understood your concerns.
This is about you and your son both having probable pin-worms.
The treatment is obvious by taking the medications for pin-worms and to be repeated after 15 days.
At the same time eradication is very important by the following ways:
Send the stool samples for three consecutive days.
Also get blood tests to see id there is
eosinophilia.
Wash the hands with soap and water on every visit to the bathroom.
Use fresh boiled and cooked food only.
Boiled and cooled water.
No outside or packaged foods.
All the members of family should be treated simultaneously.
Paring of nails and no nail-biting.
All these measures surely help to have eradication of worms from your family.
