A method for producing a non-human mammalian model for neurogenic pain is provided, which includes altering a peripheral nerve of a non-human mammal by non-surgically placing a gel substance into the fascial tunnel through which the peripheral nerve passes. The placement of the gel substance leads to one or more pain behaviors thereby producing the pain model. Also provided is a non-human mammalian model for neurogenic pain so produced. Further provided is a method for screening a treatment or a therapeutic agent for efficacy in treating neurogenic pain as well as a method for screening an analgesic agent for analgesic effect in neurogenic pain.
