Flu jab reaction

[C1239]

I had the flu jab middle of last week, felt fine the next day but Friday felt pretty ropey, it cleared yesterday but didn’t feel great yesterday and today have had a really dodgy stomach! Is it likely this is just a reaction to the jab and it will clear by itself soon?

My arm ached really badly it knocked me a bit. Was exhausted

Sore arm and feeling a bit under the weather is normal, but it clears in a day or so. Upset stomach almost a week later doesn't sound jab-related.

More likely to be unrelated to the jab.
