Commiserations, Nick. At the very beginning of the pandemic I thought I had shingles, but it turned out to be cellulitis. Since then I've had ten attacks of cellulitis, two of them serious enough to have me in A&E and one of which almost wrecked my kidneys. I've been on antibiotics for a year, and, touch wood, I haven't had an attack during that time. But if there's a jab going, flu, shingles, pneumonia, covid, I've had it! Good luck.
