What makes SFN so painfully cold?

[MG (Admin)]

Would you explain the possible nervous system problems?

Please direct me to where you read this.

I found this at http://www.health.com/health/library/to ... 30,00.html and many other sites. It talks about autonomic nervous system. I have been sort of dx with that but I really think it is so and wonder why doctors have been reluctant to address it. Is there anything that can be done to help the situation? Who is the one to deal with it as the heart, bladder, nerves are definitely involved and what else could possibly be involved that hasn't yet been connected?

As far as I know and after checking the medical literature there are no neurological conditions that would produce the results you describe. It is likely that the low metanephrine level is of little significance in your situation. It is the endocrinologists or nephrologists who deal with these issues so someone from these specialties may have more info to offer.

Hope that helps

I am really confused now.
"As far as I know and after checking the medical literature there are no neurological conditions that would produce the results you describe."
What are the results you are referring to? SFN is a sign of autonomic neuropathy. Along with the SFN I told you of the other items belonging to autonomic neuropathy that bother me. PSVT is one of the cardiac arrhythmias I have. I do not sweat. From the Mayo Clinic - In people with anhidrosis, some — or even most — of the sweat glands stop working, so the body isn't able to cool itself normally. This can happen for many reasons, including:
Nerve damage. Your autonomic nervous system regulates involuntary actions such as digestion, heartbeat, blood pressure and body temperature. Injuries to your nerves that control this system can affect the functioning of your sweat glands.

My body temp varies from 95.0 to 97.6, seldom ever higher unless it is really hot.

I don't mean to argue. I am just frustrated. What seems to clear to me is like mud to others. Perhaps it's because I know the bigger picture and maybe no other person knows all the things I experience because specialties tend to do that.

Distal Sensory Polyneuropathy and Autonomic Neuropathy
Distal symmetrical polyneuropathy is typically manifested as insidious symmetrical sensory loss of small (pain and temperature) and large (proprioception) fiber modalities. Paresthesias or painful dysesthesias (e.g., burning or tingling feet) are common, though not invariable. An unsteady gait may be the initial finding. Weakness is usually minimal, even in the distal foot muscles. Ankle reflexes are generally absent, although patellar reflexes may be present. Feet and distal calves are often cold and erythematous. Slow distal proximal progression of sensory symptoms and signs is the rule. By the time that symptoms reach the knees, abnormalities often begin in the hands.
When sensory changes reach the level of the knees, symptoms of autonomic neuropathy often begin: gastroparesis, which may alternate with diarrhea, orthostatic hypotension, anhidrosis, cardiac arrhythmias, and impotence. Autonomic abnormalities can be the most disabling component of diabetic neuropathy. CECIL TEXT BOOK of MEDICINE Section XXV Neurology Michael E. Shy •

I own most of the above.

Are you saying none of the things I spoke about are neurological? Please explain your statement more thoroughly
so I can have a better understanding. Thank you.
