Thank you for the update. Sorry to hear about the discomfort and pain. For me tetanus shot never hurt either but the last booster did for DH. I noticed now it is not just a tetanus shot but unfortunately also a booster for diphtheria and pertussis, a shot my kids react to poorly too.DH had a very sore arm also while I did not with the combo DPT shot.I was told they no longer give the single tetanus shot. My nurse asked me if I wanted a tetanus booster and I found out when I looked on my medical records that they had given me a combo DPT booster. My kids told me they no longer give plain tetanus shots.Oh so much better thank you, it is trying to drain, not where the nail poked me but down at the nail bed, so antibiotics and a special cream I have to put on it, I'm guessing it was more serious than I thought good thing I didn't wait any longer. Most of the pain has gone so that is a good thing, but my arm really hurts from the tetanus shot, I don't remember those hurting afterwards.
