Hi Rachael, Hi, Thanks for posting your query. I am happy to address your questions. Many people who receive a tetanus shot will experience some pain, swelling and redness around the injection site. These symptoms are generally not severe enough to interfere with daily activities and can be relieved using over-the-count pain relievers such as ibuprofen, aspirin and acetaminophen. For some patients, the pain and swelling are more severe; however, these effects generally subside after a few days. If they do not subside and affect your activities, will recommend you show to your clinician for a better diagnosis. Hope I have answered your query. If you have any further questions, I will be happy to help. Thanks
