Same again - 2-3 reasons.

Firstly - I think it gives a better idea of how bad I let it get.
Second- A record/reminder of how bad I've let it get.
And then - In the same way as an anti-COVID shot wasn't 100% proof against it, I'm wondering if the same applies to Shingles?  A day or three ago I thought Id been stung on the neck while out.  THEN - it spread and stayed.  If I lie down with a "Pillow" in contact with the area I can't feel it.

BUT - it's kind of  mucked up my day a little.
