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?)
