To me it sounds like Ascaris
or other roundworm. If the herbs are only aggravating them at this point, perhaps you can try medicine against Ascaris
and other roundworms although it's a bit poisonous to your liver as well. Also there might be other options that people are trying like the zapper and sputnik that photon is currently writing about. I think they are looking for a place to get away from the herbs, as well as finding some food. When they are healthy and accidentaly move out from your anus or or nose(both happened to me although not very common), they will usually turn back very fast. Just a thought perhaps you can add lots of pineapple during they day, they don't like it very much, and at night you can try eating some valerian as well, cause Ascaris
seems to be a bit sensitive to sleeping pills and herbs of various kinds. It's only a thought though. I use a zapper as well as herbs to help keep my sinuses clear from parasites although there are probably better options.
What they often do is move down to the larger intestine when you start taking herbs, but in your case one moved upwards instead. Perhaps you could try a Bowel Cleanse
as well. You should try to find a good infectious specialist that has knowledge of parasites although it's difficult to find for most.
Remember you are not alone with this roundworm problem! We are many who have the similar symptoms. Problem is they are too big for the immunessystem to handle so we have to figure out how to kill them somehow.
By the way the time one moved out from my nose was when I was in Turkey, it was 53 degrees celcius (hot), and I could barely eat. I believe it was uncomfortable in the heat or uncomfortable because I wasn't eating anything or both, and it's pretty remarkable to me when they actually try to get out of my body like that. I was drinking some drinks as well at the time, not sure if it could have anything to do with it. Don't want to be too graphic, but it might give some clues to some people on their behaviour and so fourth.
In the beginning it's a trauma for you, but it will pass after a while, and you have to focus on getting better. For me it's been such a long struggle that I don't even get freaked out anymore by knowing that I still have this problem, cause I know for example a fourth of the world population of something like that has ascaris and most of them don't even know it and that's just one parasite of all the parasites in the world! At least we are lucky to know that we are have parasites and we are a minority of all these people, so some of us on this forum actually have less parasitic load then most people out on the streets! Remember I'm not a professional and my thoughts might have errors.
