I have the same exact thing coming up when I cough; it has caused me pneumonia and I now have asthma and ephesema, and I have been to the emergency room 3 times for ct scans of my lungs and x-rays, blood tests, you name it. I have also been to urgent care 4 times because of this lung problem. I have never been diagnosed with parasites, but I contstantly fight with my boyfriend, my mom, anyone who will listen- not a soul will believe me when I say it must be worms. It looks like worms!!
