I have tried rotating herbs and meds..used 2 doses 3 months apart of huma-worm..in between using the ivermectin and valbazen. I've been tested negative for both toxocara and strongyloides, but have been on a lot of steroids in the past. (Since about 2010 on and off until early 2014). My wife however tested positive for toxocara, but her infection was not active, so her immune system killed it. I don't really know what else to do anymore. My muscles are becoming so weak that it is hard to hold my arms up to even type..I have severe swelling in my upper inner thighs which just keeps getting worse, I think it is lymphedema but the doctors refuse to listen or give me a lymphography. I get a tight squeezing sensation in my throat, I even have a little track mark on my neck (a blue vein almost right at the surface of my skin by my Adams apple). I have so many symptoms..shortness of breath, wiggling crawling sensation in the ears, anus, nose..I have actually felt them drop into my nasal cavity wiggling around. Plus, I'm slowly going blind. My vision gets worse and worse all the time. I am freaking out.
