I think Morgellons is a mixed infection. You get one parasite and that seem to trigger other parasites and bugs to be attracted to you. For example I had pin worms and didn't know it. Then they made my body more succeptable to catch the other worms and they settled in and then they make more candida and have wolbachia bacteria that gets released when they die and that attracted mites to attack me. It's just a cascade effect. You treat what is making you the sickest first and then keep treating your symptoms. There are alot more skin parasites than anyone knows about. I don't know if its true or not but a lot of stuff doesn't show up in blood until it reaches a very bad stage. I had appendicitis and it didn't show on any blood work. If I didn't go in to have a cyst removed the doctor said it would have burst in a week or so. I was lucky to be scheduled for a different surgery. Our immune systems are disabled so they are not responding as they should. Ivermectin has side effects. All meds and herbals do. You have to read them and decide for yourself if it's worth the risk. I was of the opinion that I was dying so had nothing to lose by trying the meds. I feel and look 95% better. Almost back to normal but still have alot of healing to do inside.
