This link has some informaton regarding vitamin deficiencies. Small fibre neuropathies can also present with some autonomic instability such as racing heart,blood pressure irregularities & anxiety states, due to the the same nerves also controling and regulating some of the internal functions.

You could also possibly be getting very worried and anxious in your own right, due to the PN, and unintentionally also be causing some of the symptoms.

There is alot of stress involved.

I know you have been to neuro, but have you had any small fibre testing done?
