Hi johnbishop, I don't know what's going on with the B6 but I am going to ask for a retest of the B6 and B12 and calcium. My calcium is also too high now. I did find some crucial information to this puzzle of the peripheral neuropathy. I believe it is from the Flu Vaccine I got on November 15th. Yesterday I found my blood work from the day I had the flu shot and the Physician Assistant had run my calcium level and my calcium was perfect. After the onset of this peripheral neuropathy, I was tested for calcium by my new medical doctor and she found my calcium is too high now. The culprit goes back to the Flu Vaccine. No one knows our bodies better than we do.
