Might Lysine be worth a go? Not sure if it works as well on shingles:Yes - it is a recurrence of Chickenpox which has lain dormant in or round nerve cells since original infection (for me, that was pre-1962).
I had two AV vaccinations in early 2021 - both in left arm. After a few months, there was still a very minor skin issue. I'd keep finding tiny blisters around the injections sites. I'd touch the area like when we fold our arms and feel a tiny rough/dry patch. A quick scratch and a tiny amount of clear liquid would appear. In itself, absolutely nothing. I did Yellow Card it as it was not a listed side effect.
Between my Pfizer/BioNTech "booster" (in my right arm, by choice) in mid-November, and mid-December, I got some very minor discomfort in my neck, under my chin, etc., which I thought could have been due to thyroid issues (I take thyroid hormone every day).
GP had a look/feel and decided it was probably nothing. But said to go back if it changed.
Carried on pretty much the same until two weeks ago - when the shingles appeared on my left neck/shoulder/ear/scalp. The overlap between the areas affected by the earlier discomfort and shingles was close - though shingles has been considerably more extensive.
I am neither convinced there is a causal relationship - nor that there isn't.
Regarding cancer, I recognise what you say, but am still sceptical in every direction.
BTW - The blisters have become scabs. Continue with itching, pain, poor sleep and generally feeling sorry for myself.
