TDAP Shot

I feel like my doctor didn’t inform me about this at all. I only knew what it was from people posting on Glow and thought it was just for whooping cough. Well I got it yesterday at my appt, again without them telling me anything and having to sign a consent form. And holy crap my arm hurts like 💩. It kept saying it felt like it was a tetanus shot... looked it up and low and behold it is tetanus, whooping cough and something else!! I would have gotten t regardless but I hate how miss informed I am from my doctors... anyone else feel this way??
