I said "might have been." Your link and most links with general information on shingles won't address the issues of misdiagnosis and recurrent zoster in immunocompetent persons.No, it doesn't.
I don't. And I already mentioned where the symptoms were: upper left-side torso (heart region) and scalp.
Signs and Symptoms (not the best web site, but I like the clear presentation that they give, and it seems to correspond to what other, more reliable sites say):
No.
No.
I know that these symptoms are by no means as conclusive as lab tests, but shingles still seems to be the most obvious diagnosis in my case. That the pain wasn't so bad the second time around, 15 years later, may have been due to the medicine I got.
Herpes Zoster Differential Diagnoses
See link for the list.Diagnostic Considerations
Herpes simplex virus (HSV) infection may be recurrent and may appear in a dermatomal distribution, mimicking herpes zoster and leading to misdiagnosis if no confirmatory laboratory tests are performed. [68] Lymphangioma circumscriptum may occasionally also resemble herpes zoster. [69]
In severely ill or immunocompromised patients, general central nervous system (CNS) involvement can be observed in the form of meningoencephalitis or encephalitis. Such presentations are indistinguishable from other forms of meningoencephalitis, though other evidence of acute herpes zoster usually is present. [13] Cerebrospinal fluid (CSF) studies frequently reveal pleocytosis without elevated protein. These infections can be-life threatening.
In addition to the conditions listed in the differential diagnosis, other conditions that should be considered include the following:
Why do so many clinicians believe that recurrent zoster is common?
...more than a half dozen peer reviewers and journal editors who have summarily dismissed our attempts in the past 2 years to address the issue of recurrent zoster in immunocompetent individuals. Recurrent zoster, they contend, is not reported in the literature because it is a commonplace occurrence. Is that really the case?
Articles dating back to 1900 purport cases of recurrent zoster, but most of these reports predated routine laboratory testing for varicella zoster virus (VZV), ... reports as early as 1950 noted that HSV could clinically imitate herpes zoster [2]. Ironically, there are actually more laboratory-confirmed cases of misdiagnosed recurrent zoster in the literature than there are of actual recurrent zoster in immunocompetent patients. Heskel and Hanifin described three patients initially diagnosed with recurrent herpes zoster, but all with HSV by culture, again raising the question as to whether earlier cases of recurrent zoster represent instead misdiagnosed cases of HSV [3]. ...
A colleague in internal medicine spoke to us about a case of recurrent zoster in her clinic. This patient was seen by several different physicians who all concluded with the diagnosis of recurrent zoster. After seeing our review of the literature, she subsequently performed laboratory testing on this patient and confirmed the diagnosis of HSV-mediated zosteriform simplex. There are several other patients in their clinic who are also thought to have "recurrent zoster". We predict that laboratory testing of these patients will confirm what is already demonstrated by the evidence at hand: recurrent zoster in the immunocompetent is an extremely uncommon event.
(1984 and behind a paywall) “Recurrent herpes zoster”: An unproved entity?
Physicians sometimes misdiagnose recurrent zosteriform herpes simplex virus (HSV) skin infections as “zoster” or “recurrent zoster.” Misdiagnosis can lead to inappropriate therapy with potentially harmful consequences, particularly in patients with ophthalmitis or immunosuppression, in which early institution of the correct antiviral therapy may be crucial. We report three patients who were originally misdiagnosed to have recurrent herpes zoster skin infections before we cultured HSV from their vesicles. We suggest: (1) that most recurrent zosteriform eruptions are caused by HSV; (2) that “recurrent zoster” has yet to be documented; and (3) that the diagnosis of “recurrent zoster” be reserved for those patients who have laboratory confirmation of recurrent varicella zoster (VZ). Viral culture or examintion of vesicle contents by indirect immunofluorescent technic can provide definitive diagnosis of the etiology of a zosteriform eruption.
Misdiagnosis is more common that actual recurrent zoster in immunocompetent persons. Doesn't mean it never happens but it does mean just because a doctor tells you it's recurrent zoster, without a culture it doesn't mean the diagnosis is correct.
