It is horrible but the worse pain I have endured is when they have been in my eyes and head...that pain takes on a whole other level...like 10 out of 10 pain. I don't know but I have had disseminated worms for 17 mths now and constantly on either herbal or meds. I believe mine are strongyyloids & their larvae.all my constant tests come back negative except for hommnius bactocysts but everyone has these in their bowel but I just have higher levels. Anyway I think they are definitely roundworm in nature. What have u tried?
