Is there a link between the anti-Covid vaccine and shingles?
Good evening, in May 2021, after the booster dose of the anti-SARS-CoV-2/COVID-19 vaccination carried out on my left arm, I had shingles on the same arm. After two years I still have burning and pain in my left shoulder and permanent pain in my neck, back and legs. I was diagnosed with post herpetic neuralgia. I also have Parkinson's disease. Is it possible that this condition is connected with the anti-Covid vaccination?

the causal relationship between COVID-19 vaccines and the onset of post-herpetic neuralgia or herpes zoster exacerbation has not yet been established, just as there are no epidemiological studies available that have evaluated the actual incidence of these suspected adverse events. However, some cases of post-herpetic neuralgia arising shortly after vaccination are reported in the literature, suggesting a possible link with COVID-19 vaccines.
I had herpes zoster: was it right to get vaccinated?
The cases described in the literature report an onset of symptoms at a variable distance between a few hours and a few days after vaccination. The use of corticosteroids and some antiepileptics such as gabapentin and pregabalin (drugs used in neuropathic pain) appear to have offered benefits in neuropathic pain. However, there are no documented cases of such a long persistence of the problem. Here are some articles that may be helpful:
