In June 2006 I began to be unable to sit comfortably due to a tingling coccyx. Had all the tests : X-Rays, MRI, Blod Tests etc, and all clear. This THING has taken away 2 years of my life as I am unable to walk very well because it extended to my feet (cured with acupuncture) and feel kinda 'rubbery and wobbly. I have tried to take my own lfe several times as life is not worth living like this. :-( I have just bought a coccyx kneeling stool and small table and hope they will help. I am just SO tired of it all and no explanation for it. It's very frightening. Can anyone help me, or suggest anything, please? Thank you.
