Let's talk about herpes zoster

In fact, the symptoms of herpes zoster are obvious, the typical performance is herpes zoster, and the skin lesions are distributed according to the innervation area; Because the cutaneous nerve is unilateral, it is mostly unilateral and will not exceed the midline of the body. Like most viral diseases, the course of herpes zoster is self-limited. So don't think that cure is the function of treatment. These self-limiting diseases are the diseases that charlatans like to fool, such as the so-called ancestral secret recipe to treat facial neuritis)

Apart from skin lesions, one word to describe herpes zoster is "painful", two words are "very painful" and three words are of course "very painful". Because the virus destroys the sensory nerve roots, most patients with herpes zoster will have abnormal skin sensation and pain.

Of course, there are many atypical herpes zoster, which brings difficulties to the diagnosis, such as: the pain is not obvious, herpes zoster has no rash, and bilateral herpes zoster is extremely rare. For this part of atypical patients, laboratory tests such as PCR detection of VZV DNA can be used to assist the diagnosis.

In addition, herpes zoster can occur in any skin area, the most common is the chest, followed by the head and face, then the waist and sacrum ... Of course, a small number of herpes zoster can also be complicated with complications of skin, nervous system, eyes or viscera.
