pin worm and Paragon

I am pretty sure I have Pin worm and it is something I have been battling for a few years. I have all the symptoms, itchy anus, itchy nose, rash in my arm, very low energy, anemia, hair loss and lately mild nausea at random times and mental fog. I was diagnosed with them for the first time when I was a child, and got treatment, but I remember getting re-infected a few times through the course of my life. About 6 years ago I got reinfected again, went to the doctor, got treatment, but the symptoms never went away completely. Lately I have the symptoms at its highest, especially the itching, anus and nose, nausea, abdominal pain, mental fog and rash in my arm have gotten worse . This time I haven't been diagnosed, the scotch-tape or graham text came out negative, that really doesn't mean much to me as I still have the same symptoms. I have tried DR clark treatment zapper and herbs, the only thing I didn't do was the maintenance treatments. I've also done the master cleanse for 11 days and juice fasting, all this in the past 2 years. I am tired of them, I feel a constant itch now, not only at night, but at random times during the day as well besides all the other symptoms. Lately, I have also been taking a lot of of raw milk kefir which is supposed to have plenty or probiotics, but I've noticed that I feel them more since I've started taking it, not sure if they are dying or if it is helping them to reproduce, or maybe it is a coincidence. I have been paying close check of my stool and clothes, but I can't say with 100% certainty that I have found one dead much less alive. I know how they look from when I was a child, then I remember picking a few and showing it to my mother.
I've been considering taking Paragon for it and would like to know what your suggestions would be. I know this is something I will have to repeat a few times, so if you have suggestions on that as well and I've read the hygiene suggestions which seem long and tedious, but I guess its is something that needs to be done.
