I am experiencing inching and anus cramps from 1 year and with some search in the web I came to know that it is a pinworm as I too can see a white parasite in my underwear at night. My grandmother says that it will be killed own its on and no need for medication but I feel it is because I read it can lead to urine or uterus infection or so. I'm really worried doctor. Shall I consult a doctor or try some home remedies. please help doctor. Will I died? It has been 1 years though I have been experiencing this.
