What should you know about pain after tetanus shot?

The vaccine stimulates your immune system, and local inflammation can make the upper arm sore when touched or moved. Some people also feel tired, develop a mild fever, or notice a headache. The soreness does not mean the injection has caused tetanus. Keep track of whether the discomfort is settling or becoming more intense, and mention any previous vaccine reaction to a clinician.

Move the arm gently rather than keeping it completely still, and use a cool, damp cloth over the injection site. Rest, drink fluids, and follow the product or clinician advice for any suitable pain medicine. Do not rub the area forcefully or apply unadvised creams.

Get urgent help for trouble breathing, swelling of the face or throat, widespread hives, fainting, or sudden severe weakness after vaccination. Contact a clinician if arm redness or swelling is spreading, the area becomes very hot, fever is significant or persistent, or pain is worsening instead of easing. A new symptom after a shot may have another cause and should be assessed on its own pattern.

Is this reaction within the expected range for this vaccine? Which pain-relief medicine is suitable with my health conditions? When should I report a continuing reaction or discuss my next dose?
