You need to have a serum blood test for strongyloides (ELISA). This test is available at Quest Laboratories and other labs. You NEED TO KNOW.
Your situation sounds like strongyloides and ivermectin is the drug to use--not albendazole.
You can get it online from overseas sources such as Mexico or India. You can also get it at your farm/feed store in the form of a paste for horses. Most on curezone probably use the horse paste.
I, too, have strongyloides and it will be difficult, it not impossible, to eliminate. But you must try, as doing nothing could potentially be fatal. I'm not trying to scare you, but this is the situation.
