me too
 

I too have the same symptoms.
it feels like Icy hot has been injected into my feet and lower legs.
Cant sleep do to this.

I was just tested for Paraneoplastic syndrome. The panel came back negative but positive for N type calcium channel AB.

I dont know how it can be negative for the over all panel but positive for a key marker like that.

Anyway it tool my doctor almost a year to order that test.
you might want to suggest this to him/her.

I am very scared and can not get anyone to tell me what this could even possibly mean.
