Hi! My baby is 3 months. 2 days before we vaccinated( painless injection). but for continues 7 hours from night 12 to morning 8 she dint sleep. what could be the reason?

A. Post vaccination swelling may be a common thing specially after DPT vaccine which may be painful for two or three days and the swelling may remain even up to month so if it is nohit causing any pain or other symptoms nothing to worry. Swelling can be reduced by giving ice fomrentation locally and paracetamol can be given for fever or pain. Thrombophobe ointment can be applied in acute pain and swelling .
