I don't know what parasite you are dealing with, I have roundworm, and occasionally I would get some larvae migrate to my sinuses and ears. Obviously lungs too, but I always seem to get those with cleansing in general.
All sensations and movement stop by using a drop or two of diluted Oil of Oregano. Maybe like a tablespoon of purified water to a few drops of the oil. It would make sense that this getting to the sinuses would work itself to the lungs also maybe? It take some getting used to, but it works for me every time.
