In 1999 I began developing tunnel vision over a period of weeks. I had great difficulty performing my pc maintenance duties in an RTP, NC lab. I was very dizzy, had no peripheral vision, suffered severe memory loss and confusion. I went to my physician at Duke medical center in Durham and was told I had a psychosis and was sent to a Duke psychiatrist . He told me I needed medication for severe mental problems and treated me like I was nuts. I became angry and told him something physical was wrong but he refused to listen.
I went to a country doctor in Mebane, NC and told my story. He ran blood tests and informed me I had a severe B12 deficiency. He started me on B12 shots. Within a couple of days all my symptoms had disappeared. He told me many people in nursing homes were misdiagnosed and only needed B12 shots to return them back to normal, that it was sad. My insurance bucked on repeated B12 shots so he switched me to a red, thick,nasal injection from a plunger device. later I discovered sublingual B12 liquid from a dropper which I still use daily to this day. This is disturbing that my life was almost destroyed because of misdiagnosis.
