rectum for two weeks with masking tape to prevent it from Put eggs , and get O2 ,but it suddenly become so itchy with blood , so I stop it , but when I removed the tape for three day I felt that the worms start hatching , it is seems that all what I did is the accumulating of the eggs , then when I remove the tape , the O2 became available again, and the eggs started hatching , so help , we are in the 21 century and I am unable to get rid of pinworms , I don’t make any relations with girls because I don’t want anybody to suffer like me , please help , medication is not work ,
