Doctor...i year ago i had some intestinal problems..had vomiting tendency..i felt like a while gelly discharge along with my stool...also sometimes it came through my mouth...it was so dreadfull...later some food got stuck in my throught after one day i had pain in ears and later the pain spread to back side of head...it was so terrible i could'nt get sleep or place my head on the pillow. I then took metrogyl tablet as my aunt prescribed that for stomach but i never took that before...After taking that a large amount of puss like discharge came from the head...i suspect its the same worm from the stomach that spread to the head. I suspect it has spread to urinary tract also during contact..i did stool test but couldnt find anything..i would like to know weather any valid test is there to confirm this..other than stool test...Also i think it has not spread to blood as i did blood test also...which was negative...i would like to know all possible test so that i can do it as soon as possible....
