I too have autonomic neuropathy and PN. My autonomic neuropathy is actually quite severe and much worse then my PN. I take numerous medicines to control heart rate, BP, GI problems, etc. I also had to have a pacemaker implanted 8 years ago due to autonomic neuropathy. All that said, I function okay now...not perfect, but functional. There are MANY options for treatment available, so I'm not sure where you read all the misinformation about high death rate etc. You must be careful about your sources online. Best if you go to a neurologist and get a full workup (which may include tilt table, GI emptying, BP & heart rate monitoring and neuro exam) before you start worrying about anything. I feel confident that IF he confirms your diagnosis, he will also put your mind at ease about being able to effectively treat your symptoms.
