My B12 and MMA are normal. I have not used nitrous oxide for years since it increases nausea and vomiting and possibly intracranial pressure during neurosurgery.

I thought the Mayo AZ would be able to do the skin biopsy. They do not. I did find out a group at Good Samaritan in Phoenix offers it.

You are right for an idiopathic cause of a disease, there is only symptom management.

I felt like a cog on a wheel at Mayo whose sole purpose was to make money for them via testing and large copays.

I have studied at some very good places including Northwestern University and Columbia University and did not see this atmosphere.
