High blood pressure after tetanus shot?

While the tetanus shot has some potential side effects including soreness, fatigue, headaches, fever, nausea, diarrhea, aches, skin rash or itching near the injection site, high blood pressure has not been reported as a common concern related to receiving it. If you do have sustained increased blood pressure, it may be best to consult a healthcare professional, as elevated blood pressure requires proper evaluation and monitoring.
