Characteristics include inflammation of spinal ganglia with pain and a vesicular eruption along the area of distribution of a sensory nerve.
It sometimes accompanies diseases such as pneumonia, tuberculosis, and lymphoma; and it may be triggered by trauma or injection of certain drugs.
In some cases, it appears without any apparent reason for activation.
It involves the sensory ganglia and their areas of innervation, characterized by severe neuralgic pain along the distribution of the affected nerve and crops of clustered vesicles over the area of the corresponding dermatome, and it is usually unilateral and confined to a single or adjacent dermatomes.
