I just had to have a Tdap booster for school recently and I had a little muscle soreness for a day or so but no worse than any other shot.I never thought a tetanus shot hurt at all. But I always get painful muscle soreness and stiffness afterward for days afterward, that's why my doctor said I can't have them any more. I'd accidentally jabbed myself in the hand while administering a tetanus shot to a horse and I went in to see if I needed a shot and when I told the dr I react to the shots that way he said Nope.
I almost got that out with a straight face.
