Is this side effect or reaction of Flu jab (on Sunday 27th) or something else?

[BameChange123]

Hi had pre-emptive flu jab 2 days ago. Have flu jab voluntarily every year, no negativesideeffects before. After 24 hours I had headache (took ibuprofen) sore throat, felt hot (but temp=ok). Then had upset stomach (D but no V as yet). Now feeling very fatigued. Is rhis normal reaction or is it something else?

I had mine on Saturday and have felt fine. My stomach has been a bit dodgy but I have IBS so think that's due to the rubbish I ate at weekend! In previous years I think it's made me feel a bit blurgh.
