Thanks for the reply and links. Very interesting (and scary I have to say!). You've probably read my previous posts, I've just finished Humaword, feeling much better, although symptoms persist, albeit not so bad. I'll continue with Huma's advice until I can do a further course of treatment in roughly 90 days.
Think it most likely is ascaris, VERY HARD to get rid of but I will continue the fight and try everything available. I've even read that milk entices them out. Read somewhere that if you sit in a warm bath of milk this entices them out. Some days I'm so desperate I may even give it a try!
I've enjoyed reading lots of your posts and have gleaned a lot of helpful advice from you. Very much appreciated.
