I went to an appointment with neurology yesterday and this is what I found out. My B12 was 900 something, so that doesn't seem like it's low, based upon what you said. I asked the doctor about vitamin D and magnesium and he said those weren't causes of neuropathy. I am really at the end of my rope. I can't imagine this is my life for the next 30-40 years. Now I'm wondering about opiates. I told the doctor that I really didn't want to take opiates because I was afraid of what they'd do to my liver. He said they wouldn't affect it. I checked online and found something that said the liver damage is caused by the Tylenol in the opiate, not the synthesized opium. If you don't take a dosage too high on the Tylenol side you should be okay. Any thoughts on this? At this point, I'd be willing to do anything to get any kind of relief. Thanks for your help.
