If it hasn't worked by now, it probably is not going to. I went through the same thing in the beginning and Im not sure if the Ivermectin actually made it worse. After a few rounds of Ivermectin with no relief, I went to an Infectious Disease Doctor who treated me like a lepor. I was put in a exam room where I waited for two hours for the doctor to see me when I had an appt. I had no idea about Morg at the time, so I wasnt even saying anything that could be perceived as crazy. I told the doc that I had what i thought was scabies but it wasnt going away with treatment. First he asked me why I didnt go to a dermatologist, b/c this was "up thier alley." Then he started going off about crazy people who believe in aliens and other Conspiracy theories, and at the time, I had no idea what he was talking about. He ended up just prescribing me more Ivermectin, which of course did not work. Eventually the visual signs of this disease disappeared from my skin, but then theres other stuff...

I dont mean to scare you, but there's a good chance you might have what they call Morgellons.
