Hi Diana,

This is going to be tough because that is very little to go on. 

The elevated ANA does not really tell me anything since there are a number of reasons for an elevated ANA other than autoimmunity.  Even the erythromelalgia could be contributing. Although erythromelalgia can also be triggered by an autoimmune disorder.

There are some things though that I think will help.

First of all focus on building up your adrenals just in case there is an autoimmune disorder.  The production of low affinity autoantibodies is triggered by low levels of immune modulating corticosteroids.  Building up the adrenals will also help with reducing the inflammatory responses, such as with the erythromelalgia.   Here is a link about building up your adrenals:

There are several adaptogenic herbs I recommend you really focus on.  These are suma and licorice root.  The suma to help with oxygen utilization by cells and thus elevated ATP formation.  The licorice root is also a steroidal anti-inflammatory.

Something else I highly recommend you focus on is magnesium.  But not just any magnesium.  You need to look specifically for magnesium malate, and preferably with extra malic acid added.  Or you can buy separate malic acid.  Magnesium is a natural calcium channel blocker, so it can help with the erythromelalgia by relaxing the blood vessels so they do not go in to the initial contracted state associated with erythromelalgia.  Magnesium also elevates ATP levels, which is fuel for our cells and helps our cells to function properly.  The malic acid, which is the "malate" of malic acid is also an ATP precursor.  This is why I specifically recommend the magnesium malate.  Recommended dose is 300mg 3 times daily.  Do not take it at the same time as a calcium supplement since it works in part in this case by antagonizing calcium.

CoQ10 also helps to elevate ATP levels.   Recommended dose is 100mg 3 times daily with meals. Taking it with a little oil in your diet will aid in absorption.

For right now I also recommend for right now is a tablespoon of lecithin granules 3 times daily  and one teaspoon cod liver oil twice a day with meals.  Lecithin is a major component of mylein. Essential fatty acids make up a large part of the remaining myelin.  The breakdown of myelin leads to neuropathy.

You did not mention anything about your diet.  But if you are a vegetarian, raw foodist or have problems with low stomach acidity then a sublingual B12 is also recommended.  B12 is required for myelin formation and plays a role in reducing inflammatory homocysteine.

Those are my recommendations for the moment.  Without knowing exactly what is going on it is pretty much a matter of seeing how you respond to the recommendations.
