I have dealt with severe scoliosis my entire life, but issues with my hips, particularly the left one, has garnered diagnoses such as arthritis and/or calcification. Turns out, however, that I've had two parasitic worm infections since 1976, and there was a nest in my hip among a few other places! The usual herbal antiparasitics are too harsh for me, but I'm having tremendous success with the Zapper and homeopathic Cina. I urge anyone dealing with chronic issues to get a Zapper and diagnoses via biofeedback machine since worms are much harder to eradicate than bacteria and amoebas. Additionally, my boyfriend used the Zapper briefly to see what it felt like. His arthritic swelling immediately went down, however, tiny pinworms are now appearing in his fingers so I now believe the few studies I've seen stating that arthritis has parasitic origins. Definitely worth an $80 biofeedback session and a $35 Zapper.
