He told me I should be happy to leave the office with no prognosis when I became tearful. Once blood work was completed and showed the opposite of what he explained in the office no explanation was given. No change in plan made. I now live in constant pain and someday I am unable to care for myself or work..... It seemed like he didn't care. He just wanted me out if his office.
