3 years ago, I moved to a home in southern Nevada less than 20 miles from Hoover Dam and less than 300 feet from super high voltage powerline. (DUH!) Before moving here, I was a healthy, energetic, athletic woman, but soon I began having fatigue, frequent headaches, even migraines & depression. Joint after joint, tendon after tendon became inflamed & painful. I was having difficulty sleeping at night. After only 17 months, I was in so much pain, I needed a cane to walk. I saw an orthopedist, but he couldn't find anything that could explain all my pain. Hmmm... I'd heard of EMF sensitivity, but never experienced anything like this. I called in an EMF consultant. He told me to turn off the power to my bedroom every night and installed Greenwave filters in the areas of my home where I spend the most time. It helped tremendously. I was able to sleep through the night and began healing. Within a short time I no longer needed a cane to walk. BUT....I was still having lots of headaches & tendonitis in my extremities. Hmmm... So I purchased a passive, and quite expensive device, a Qi-Shield. I lugged this 3 pound device with me everywhere I went. After 6 months I noticed a definite reduction in headaches and not a single migraine, however, I still had tendonitis in my arms. Grateful for the improvements, I figured this was the best I could do. Then I heard about BluShield from a podcast by Lloyd Burrell. What was extra appealing to me was the small size & portability of the BluShield devices. I bought the home pack that included a plug in unit and a small portable device to carry on my body. The first 3 days, I felt worse with lots of full body muscle tension. But after several weeks I began to notice the tendonitis in my arms melting away. It's been about 2 months since I've been using the BluShield devices and I can honestly say I'm 99% pain free. My only pain is the occasional headache I get when the barometric pressure drops as a low pressure system rolls in. I'd say this is pretty darn good for a 68 year old woman!
