Hi there

If the one's EMG is normal and the Skin biopsy that one's gonna do is also normal (negative for small neuropathic pain), can one infer that the prolonging of his pain is psicossomatic? Maybe due to anxiety?

Or on the other hand, if a skin biopsy is positive for small fiber neuropathies and a year later is negative can can one infer his pain is going to be over?

Thank you

PSdoes a idiopathic small fibers neuropathic pain can be seen during a skin biopsy?)

IF both are normal that wouldn't indicated Neuropathy. There are a few other things that are needed to determine if the Neuropathy could be from your spinal column. An SSEP is a test that will check for damage from the Spinal Column and a Brain MRI would check for damange there. I'm pretty sure you've stated to have had an MRI of the brain and it was normal, also a cervical MRI?

IF all is negative, than it is possible that "Tingling, Needles and Numbness" could be an attribute of anxiety. Anxiety does cause symptoms that mimic a nerve illness MINUS the pain! NOW as the pain is concerned, there is something called "Somatoform Disorder", which is a mental disorder or disease that MIMICS a PHYSICAL disease! It could cause pain and a host of other problems!

Back to the other causes, you need to have your Thyroid checked, have a full run of T3, Free T4 and TSH, that could cause neuropathies that wouldn't be found by EMG or Biopsies. Also, have your blood glucose checked, 2 Hr. fast and if you re-take the 12 hour fast it may show up something the second EVEN third time around!

There are many causes for your pains, don't you let the doctor label it as a "Mental' disorder, if he does, get another opinion until you're satisfied!

Keep me updated

BTW, it isn't the "pain" that they can see in the biopsy, what it will show is a smaller amount of the "small fiber" nerves/nerve endings in the skin, OR deadened nerves.

I have Idiopathic Small Fiber Neuropathy, it was a journey, but FINALLY they found it! Good luck

Thank you Josh for your kind Reply.

I don't have any desease that may be the cause for my neuropathic pain (I did all kind of exams). My pain was dued to a stupid exercice with dumbells. However I do have small neuropathic symptoms, that are decreasing from day-to-day, that is why I'm gonna do the biopsy. Now I'm affraid I'm the one who is prolonging that pain (with my mind, stress, etc...)

Anyway, what I wanted to know is that: reenervation of small fibers on the skin after a nerve lesion, means that the pain should stops.

By the way how did they find your idiopathic pain?

Regeneration means the pain COULD stop! Even tho the problem is fixed your body could still send the pain signals to your brain.

My Neuropathy was found by an EMG and my Quantitative Sensory Testing (QST) was all kinds of abnormal! They've not found the cause as of yet, (which we're working on), so I'm still labled *IDIOPATHIC* !

How do you know that the dumbbells are what caused your pain for sure?

Have you had a SSEP test yet?

Sorry Joshua, but what is a SSEP test?

By the way, have you heard about Neurotrophin NT 3? And that sea coral? Do you know why is taking so long for them to be approved by the FDA and available to us?

Wouldn't that basically be like fibromialgia?
They don't know what causes the pain in that disorder either do they? And yet the people who suffer from it are in a load of pain.

However, there are mental disorders that cause "pain" when there is no pain AKA psychosomatic pain.

But, if you have a negative EMG (no large fiber damage) and negative skin biopsy (no small fiber damage), I think we can rule out peripheral neuropathy at least.

A MRI of brain and spine would be good, to see if its a central nervous disorder.
