All these years I've been hearing that tetanus shots hurt a ton. Well I got one on Tuesday and two days later I'm still waiting for the pain to kick in. I've taken no pain medications during this time period either. In fact, the needle itself didn't even hurt one bit. I watched it go in and I felt nothing. It was odd because I was expecting it to be more painful. I lifted hard the day of and ran about 3 miles yesterday and so far the only pain I can feel seems to be the normal pain I get from working out. My other arm feels exactly the same. So I guess if I had any advice for those getting a tetanus shot it would simply be to work out hard the day of and get your blood flowing, especially around the area where the shot was given. I got several immunizations including multiple shots and I feel absolutely fine. I was told I should be sick to my stomach and that I wouldn't be able to lift my arm. I guess I got lucky? I've noticed none of that so far.
