Hi I have had 3 flu injections since being diagnosed with Type 1 three years ago. My previous 2 injections produced no adverse side effects (not even raised blood sugars). This year I had my injection on 9th October and ever since I have had a toothache like pain and lots of stiffness in my left shoulder. Has anyone else experienced this by any chance after having their flu jab or could it be just coincidence, thanks Carole
