For parasites in my sinuses I used the following treatment successfully.
A tibetan tea for eliminating parasites in the sinus cavity combined alternatively with Ivermectin liquid and Valbazen liquid.
I brewed 3 cups of the anti-parasitic tea daily and flushed the sinuses 3 times per day. First just flushed with the plain tea. Later, mixed a cup of it with 2 tablespoons or so of oral Ivermectin (Sheep Drench) and used a neti pot to flush the sinuses. Later mixed a cup with a tsp of Valbazen and flushed before bed.
Made sure to cover every part of the sinus (looked at diagrams on line) by shaking head back and forth and up and down while holding nose. Lay down on floor and rotated head back and forth for a minute. Did this daily for a month.
You would just ask for the anti-parasitic tea to drink, the red anti-parasitic powder to take with the oral tea, the anti-parasitic tea to use as a sinus wash. I forgot to mention that I also used another product which was a medicinal snuff; which is a pinch of powder to inhale in each nostril 2 times a day.
So you would ask for:
1) antiparasitic tea to drink
2) antiparasitic tea to use as a nasal wash (different from 1st)
3) antiparasitic red powder to take with oral tea
4) antiparasitic medicinal snuff
I do not know the Tibetan names for these, but these are the only antiparastic meds he has so there will not be a confusion. The doctor mixes them himself based on his training. And the website has the email address: http://www.shakyadorje.org
Also, I should add that I am in no way related to this doctor of Tibetan medicine financially or any other way. He is really highly respected and came highly recommended by multiple people. He has been practicing in Toronto for decades and is considered a very honest, smart and valuable member of the Buddhist community. He also travels to 3 other cities every few months to treat his patients. Someone posted something about profiting from the suffering of others. This is not what I am doing. I am telling people of a viable solution that cured me of an incredible misery since the question of sinus worms came up on the forum discussion.
This is what I used to get better. Worms in the nasal cavity are a complete nightmare. I left my post anon since nasal worms were too distressing to talk about a lot.
And as I said, I mixed the nasal wash with iver and valbazen alternatively each day.
And I took oral iver and valbazen at the same time.
Oh, and in case you were wondering: I started by trying just valbazen and iver in water for 2 weeks and it did not get rid of them (while also taking iver and valbazen orally). But with the tea and other Tibetan meds it did work.
If this works you are a God!!! So far after months of searching, you are the only one with a success story. Thank you for the links and helpful tips. Much love from a thankful warrior of this insane battle!
