I was diagnosed with hookworm, along with a lot of other stuff. I had a bad cough, fever, and horrible IBS for months. I was diagnosed with IBS and malabsorption disorder and put on a prescription-strength vitamin therapy. I had horrible leg cramps from potassium deficiency, even though I ate a lot of potassium rich foods. Hookworms drink your blood, so I was anemic all the time. I had larva migrans too. The first herbal cleanse I took, they started coming out everywhere. They were too big to be strongyloides, although a lot of them came out too. There were tons of them in my feet (where they probably got in) that came out as something like shards of glass out of the bottom of my feet. A couple tore through my skin so badly I still have the scars. They are nasty creatures.
From what I hear, castor oil helps with them as well as papaya seed.
