Thank you for caring mrs D. I have been tested for heavy metals. I was hospitalized for 5 days in Dec. Extensive work-up. Many more blood tests from the neuro-muscular specialist. I am still waiting to see the results personally. The neurologists have been horrible with feedback. I remain hopeful. His nurse sent me an e-mail stating that he could find nothing except evidence of neuropathy and he refused to fill out my long term disability papers for my employment and temporary disabled ID card. I cannot walk very well and certainly cannot drive. What a TOOL!!
