The important issue here is strongyloides. How were you diagnosed, Elisa?
I, too, have strongyloides. I have passed a few large creatures which I'll never know the name of. The key word here is "few". They will most likely be cleared out with the strongyloide treatment.
All your symptoms match mine and I believe your strongyloides are alive and thriving. I suspect you know (are probably already doing) the correct treatments. But if you're not, you should be.
