I suffer from severe bone decay and walk with a limb for about two years I was a celebrex freak, at night my leg and hip had a song very familiar to those of us suffering from arthritis, OUCH, OUCH, OUCH !!! The solfeggio frequencies help to eliminate my pain 99.9 %. Hey now I can walk without a limb and I sleep like a baby. I have not heard the familiar song for almost a year now. Hey it WORKS !!! Hooray !!! I am just extactic with joy. My lungs did not function and my heart was severely damage , now I can run and lift objects without pain or getting dizzy. At work I am responsible for remodeling 3 buildings . The last year due to the solfeggio frequencies I can honestly say I am a new man. I hope this helps. Try it you'll like it. The solfeggio frequencies has become my life work. Why do they work ? It is like getting a mind and body tune up
