Filipe,

I think the problem is anxiety or something musculoskeletal. You say that your anxiety medicines help the pain could mean that the pill is either relaxing the muscles or your anxiety issues. I don't think anxiety medicines have any value for nerve pain? I could be wrong tho?!? Anxiety can cause tingles, numbness and a feeling of a "glove". The muscles can cause a LARGE variety of pains.

If you were in fact experiencing "Chronic Neuropathic Pain" I think something would've shown up on the Biopsy or the Several EMG's you've had. You also said your complete Neurological exam was normal, that for me really shows it isn't the nerves, small or large. The EMGs most likely would've showed some kind of nerve change as well. The biopsy would've shown a decrease in the Small Fiber Nerves or would've show damage. "Chronic Neuropathic Pain" is a diagnosis you don't have, you're not diagnosed with neuropathic pain, I don't think it's neuropathic and obviously none of the doctors think it is neuropathic.

IN MY OPINION, this isn't a peripheral nerve problem, IF it is a problem with the nerves, it's central. I for one think this is a musculoskeletal issue considering you injured your muscles or soft tissues with improper lifting technique.

STILL, with a normal Neurological Exam, it doesn't make ANY sense that it could be the nerves, CAN you have a normal Neurological Exam (QST and so fourth) a normal EMG and a normal nerve biopsy with nerve malfunction or nerve death?
