Worms definately. The same type a shocking number of people are finding they have....as to the exact species, we don't know. It is as if the typical human roundworm has morphed into something very difficult to detect, kill, and has become more harmful and damaging to the human body.
The reason that the person above asked is that you seem to be getting lots out, which normally does not happen. People here go through long cleanses, and take lots of horrible stuff, only to hope to have the evidence of dead worms that you seem to get out without effort.
Can you think of anything you might be eating, spicy, garlic, or teas you drink, medicine you might be taking.....that might explain how you are getting these out?
Our immune systems should be helping to kill them, but these things are stronger, and hide. I guess it's possible that you have such a strong immune system, but I really doubt it since you are still having problems.
Think abut it and let us know, you might be on to something that could help others!!
