Toxocara would be the most logical for you if your wife is already positive. have you tested your immune system? perhaps you are false negative. I'm as bad as you, now my head is concerned, my veins are very pronounced, sometimes I think it can only be myiasis, because it is so agresiv and you can see it from the outside, my face has dimples to ask where they moved that something finally went through my nose, my forehead is where the red. there must be something happening in the brain, because I had an ischemia. Yes, I am also very scared , especially because we dont have a doctor, who deals with as, we are left to asself and forums like this one. I envy people who have a diagnosis. if you have Toxocara, febendazol is the right medication, maybe you should stop ivermectin and doxi and febendazol reduce dose, so that your body can destroy it slower now. in the literature
Toxocara do damage to tissues, what happened with you and me, I am negativ too.
