My doctor knows about parasites especially worms but she referred me to parasite test which eat which came back clear even though I know I have them. I don't think the medical profession is very well up to date about parasites unfortunately. I did not know that if you poke your stool with a stick that you would be actually able to see the parasites so I will try this since I'm in the middle of my paragon treatment... I know I definitely have symptoms of being more tired than usual while I'm on this treatment... But then I always bounce back the next day after being tired and feel much better. I wish more doctors would prescribe an annual de-wormer or parasite cleanse that can also be purchased without a prescription...
