Shingles is actually what is commonly referred to as shingles. If shingles occurs frequently, or if shingles has already occurred and the lesions are gradually darkening, the dark part may be a form of epidermal necrosis. This epidermal necrosis does not mean that the herpes zoster is almost ready, but it may be a local inflammatory reaction and skin necrosis, or it may be a fixed process in the course of the development of herpes zoster. Therefore, in this case, it is not possible to say with certainty that it is well or not well, but it depends on the specific manifestations and the specific state of shingles during the onset of the disease or during the course of the disease.
