O my gosh...I'm sorry you had to go through that, but I'm glad you were able to produce proof. I've noticed that there are various layers of healthcare workers, I had a similar situation when I had such a bad infestation in my sinuses. I went to an ear, nose and throat specialist. I was able to produce samples for them in person, his assistant saw them and thought they were worms, and so did he. They sent the sample out to the lab and because there were no eggs, it came back negative. When I came in for the follow up, I was shocked to see them all act like they never saw any worms once the tests came back negative. Instead of believing their own eyes, they chose to believe the lab tests. So lame, I was disgusted.
One weapon we have is to rate these doctors on the Internet. We all have a voice and a way to get it heard, I know it's not a solution, but every doctor who has failed me in this manner, I expose.
By the way I got rid of the sinus worms by flushing with a solution of water and saline and also water and small amounts of organic apple cider vinegar (it stings, be sure to dilute!).
Congratulations on getting that big worm out! Take care, okay?!!
