Now, thanks to this thread, I know what I had in nov-2017. It was on my back just below the left shoulder blade. Not very painful or itchy and at that time I didn’t know what it was. It just faded away, but I took a photo before anyway….
It was seven years ago, so it’s said I have a 5%-risk/year of having it again.
Going to do the Shingrix vacc this autumn, when I return to Thailand.
Have checked with a hospital in Nakhon Sawan and costs around B 5500 for both.
Very costly here in Sweden (SEK5500 = US$500)
