Yesterday I got my ‘booster’ covid shot from pfizer. Experienced some light discomfort in the evening at the same day. Nothing special. But also my bg values were going low in the evening, night and this morning i could even skip a shot of insulin. Anyone experienced low bgs after the booster too? Second effect which was a lot less fun: i went for a run this morning (i do it almost every day). The first mile went ok but then suddenly got medium too heavy pain in my back on the right side. So just googled if there are reported any side effects on the kidneys, and it turns out the EMA has indeed requested data from pfizer related to kidney disorders: https://www.fiercepharma.com/pharma...h-moderna-covid-vaccines-and-skin-condition-2 The pain is less now that i stopped the running, but still there. Very strange. Hope it is unrelated, but never had something like this before.
