Please help

I'm convinced i have parasites and am sure my family does also. My daughter is constantly complaining about itchy privates and rear. I have a multitude of problems, digestive disorders, skin problems, constant fatigue and muddled brain, joint pain especially in my hips, headaches, sinus difficulties - especially in my ears (pain and squishy fluid noises). I'm only 30 years old - I'm too young to feel so crappy!

I think that parasite treatment is necessary but I have no odea what works and I'd like to get one that will kill as many varieties as possible, not just 1 or 2. Some are very expensive, some are not so expensive. What do you all recommend?

I'm looking at Dr. Natura's Paranil and Paranil Jr. for children. Are these effective or is there something better? Please offer some advice, I don't want to see a doctor and I'm too embarrassed to talk to anyone about this.
