Hi, thank you for posting.
I have gone through your query and I understand your concerns.
All your symptoms show that you suffer from colopathy that is manifested with oxyure vermicularis infection.
In these cases the following tests are necessary:
1. Stool culture.
2. Abdominal ultrsound.
4. Complete blood count
5. Urine test.
Contact your infectologist and your gastroenterologist.
All the best.
