MS and flu

Hi my ms friends… well I’ve had ms since 2003! I have had ups and downs with it but generally ok ish… I went for my usual flu jab yesterday which was fine but a little later after it I was stood paying for my shopping and I started having bad tremors abit like Elvis?! (everyone probably thought I was drunk?!) I couldn’t stop them till I got home and sat down, it was horrible and scary. Has anyone had similar from the flu Jab or do you think its just usual ms type thing? Thanks for any comments n have a great day Lindsey x
