Yes, I agree. We never use the word "cure" here.

Depending on what is causing PN... the closest thing to a "cure" is for those who don't really have a true PN, but have paresthesias instead.
Paresthesias are symptoms of something else, and in certain cases when the primary problem is fixed, then the paresthesias go away.(the symptoms stop). It is a fine distinction, but it can happen. Hyperventilating or having acidosis from something can cause tingling in the periphery but it goes away when the situation changes and the hyperventilation is corrected. That is one example.

PN symptoms that come and go may be paresthesias. PN symptoms that remain constant probably are not.

Some doctors just tell patients things that are inaccurate. A doctor may just believe a person has CMT, and tell them that without further testing or family history investigation. If that were the case, one would have to realize it was not a real diagnosis.

In the opposite vein, I am becoming concerned about the news coming to light about the tainted methylprednisolone injections given as epidurals and joint injections, and their perhaps being a trigger for
nerve pain. The latest news suggests this was going on way before it was discovered... so people may be suffering from fungal infections in joints, or the spine for all we know, those who had epidurals, etc.
