I actually had a systemic parasitic infection my respiratory system was involved. I did at one time expell two three inch long and a quarter inch thick with ridges and triangle shaped head red black - assuming it was blood filled- worm it was nothing I had ever seen before- from my sinus.I was very ill and unaware I had a immune defiecincy leaving my body open to a host of bacterial fungal viral and parasitic infections. I had travelled extensively, had eaten sushi- loved the raw fish- for over thirty years,done all the things I should have avoided given my staus of a immune deficeint person. I did do a saliva test and tested positve for having or having had- toxoplamsa, trichenella, tapeworm, hookworm and roundworm. I needed extensive treatment with parma meds and also did an inhalation treatment with pharma meds compounded for me by a pharmacist.I was a slave to saline rinses. It took months of treatment.During treatment I expelled Tapeworm and hook worm. I always saved my samples and showed them to my doc for visual identification.Nothing like making a doc wide eyed. I have been parasite free for some time but do include an annual deworming in my yearly plan given my immunity status Your photo is not anything like I expelled but I cant tell you if it is a parasite or not
