very likely these are Ascaris (I would say Ascaris megalocephala) - they get everywhere in your body and are very long - do you feel them elswhere??
they go into the sinuses and on the scalp and around the ears, also carry a heavy load of candida
because they get systemic, it's extremely hard to get rid of them
repeated herbal protocols help, but personally I got a significant improvement only by using frequency generator (you might use the zapper but it doesn't help too much, sometimes it just makes them more active)
Colloidal Silver or vervaine blue works on killing them - but you might have different Ascaris and I am not sure if Colloidal Silver would work for them - it works for megalocephala because they are very thin (but long)
