10. Patchy erythema
There’s also the possibility of developing patchy erythema instead of vesicles with fluid. As the name implies, patchy erythema looks like a reddened skin region in patches. In some cases, these patches are also indurated. In other words, the skin becomes slightly hardened. All of these manifestations, including patchy erythema, are limited to the affected dermatome corresponding to the nerve initially taken by the disease.
