I know it's been a long time?
Did you get rid of them?
I recently went through this and my symptoms were 3 months dry cough which to my surprise is a symptom of pinworms and of course the classic wriggly itchy rectum.
The product that worked for me right away is by Eclectic Institute and it's called Intestinal support, it's got the Wormwood and Black-Walnut and clove concoction.
In addition to that, you have to go thoroughly hygienic because the eggs are around and the worms too and cause re-infestation.
Clean sheets, wash every few days if you can, clean hair, clean underwear all the time, clean hands, especially under the fingernails, you may get a toothbrush specifically for under your fingernails. Good soap like Dr. Bronner's peppermint soap.
Eat parasite/pinworm killing foods
I think the strongest are
pineapple, I cut up a fresh one, that actually got rid of my dry cough after eating a whole one 2 days in a row and once I stopped the cough came back until I would eat a pineapple a day again, this went on for a week or so until I went on Eclectic Institute intestinal support
eat 1-2 bitter melons each day for 7-10 days. It is available in Asian markets.
pomegranates/pomegranate juice, I think best to eat fresh
papaya/ papaya seeds
herbs/spices that kill pinworms/parasites
Grapefruit seed extract
cascara sagrada, Wormwood seed, cloves, Echinacea, goldenseal, and Black-Walnut .
