Hello - There are certainly parasites and larvae that can live in the eyes and in the sinus cavities too. For example: pork tapeworm larvae LOVE the brain and upper head area (eyes, sinus cavities, etc.). Many species of parasites will have eggs that travel around the body - then hatch - then the larvae travel to a different spot to grow bigger - then they'll move to the adult home in the body to lay eggs - and the cycle starts all over again.
He needs to do the 30 day parasite cleanse and if possible, you and everyone else in your house needs to do it at the same time he does. Have any other family members had any illnesses in the past 2 years too? ANYTHING - like more colds, allergies, digestive problems, skin problems (including rashes), etc.? Usually if one member of a household has parasites - the whole family does - the symptoms will just show up differently in different folks. 70% of parasites are microscopic while only 30% are of the visible variety - but they all can cause severe damage if left untreated.
As you probably already know, parasite eggs are microscopic and can be EVERYWHERE. I invite you to read the information on our website http://www.humaworm.com It has a lot of helpful information about parasites and has NO gory pictures! Let me know if there is anything I can do for you. Thank you!
