I have had a lingering but fairly mild cold for about 4 weeks now (am 34+5 and insulin dependent) and have on and off felt a bit rough. However I went up to my GP yesterday for an unrelated issue and while I was there got my flu jab. Within 5 hours of having it I felt bloody awful: really high temperature, chills, aching muscles, horrendous cough, sinusitis, earache and a really tight feeling in my chest. Have I been unlucky enough to have caught the flu before my jab or has anyone else had this extreme reaction to the vaccination? Waiting on some advice from NHS direct right now.
