My 5yrs old son has been vaccinated on 16.07.2025 and his vaccinated place is still feel hard with little pain. Is it usual or I have to consult with a doctor.

A. You should always do cold compress on the vaccination site after you get the vaccination done and Thermophob to reduce that pain and swelling if you haven’t done till now you should start doing it twice or things are not better then yes you should consult your doctor once
