Caller reported that it was back in that era that she started having high blood pressure and it's been more than 10 years. Caller reported that she has some peripheral neuropathy.

Caller reported it had to have been at least 10 years if not more that she's had peripheral neuropathy. Caller reported that she has a PhD in physiology.
