The invention provides compositions and methods for treating neuropathic pain. Specifically, the disclosure provides a polynucleotide comprising a trigeminal ganglion (TGG) or dorsal root ganglion (DRG) promoter operably linked to a recombinant nucleic acid encoding an endonuclease that binds to a nucleotide sequence in the human colony stimulating factor 1 (hCSF1 ) gene and a method of using the polynucleotide or a vector comprising the polynucleotide for treatment of neuropathic pain.
