Do some research on roundworm and Tapeworm and see if any of it fits. This is what I did and finally something clicked for me and off I went. I just finished my first 10day round of Alberzole for Ascaris. I had symptoms in my lungs that finally nailed it for me. I will look for the protocol about the meds I got from here and share it with you.
There seems to be no good answer on how to figure out what you have, so I just spent a lot of time reading up on parasites. Looks like I only have to deal with the ascarsis.
