Embodiments include a cryogenic device for alleviating pain by cryogenically treating a nerve, the cryogenic device including a handpiece； a needle coupled to a distal end of the handpiece, the needle including a needle lumen, the needle being configured for insertion into a skin of a patient along an insertion axis at a site laterally displaced from a treatment zone proximate to the nerve. The needle is configured to resiliently bend after insertion away from the insertion axis, such that at least a portion of the needle is adapted to traverse a skin layer laterally toward the treatment zone. The device includes a cooling fluid supply tube extending distally into the needle lumen； and a cooling fluid source, wherein the cooling fluid source is coupled to the cooling fluid supply tube to direct cooling fluid into the needle lumen.
