What are the dorsal root ganglion (DRG) levels associated with groin pain?

The dorsal root ganglion (DRG) levels associated with groin pain primarily relate to the distribution of nerves innervating the area, especially the sensory nerves. Pain in the groin region is often connected to the sensory innervation provided by the T12 to L1 nerve roots.

These nerve roots correspond to the lower thoracic and upper lumbar segments of the spinal cord. Sensory information from the groin travels through these levels, making them critical in determining the origins of groin pain. The T12 and L1 segments are particularly crucial as they provide nerve supply to the skin and deeper structures around the groin, linking the DRG levels directly to sensations experienced in that area.

In contrast, the other options involve lumbar and sacral levels or higher thoracic levels, which do not adequately correlate with the groin pain sensation as effectively as T12-L1.
