36
Where does shingles hang out?
* Dorsal root ganglion, which are just outside the spinal cord. * It's where the cell bodies of the sensory nerves are congregated * The ganglion are just outside the spinal cord. They hang out in those neurons and cell bodies dormant, sometimes in the future there's a triggering events where they migrate back out to the site on the skin where the lesions appear
