My son is 1.5 yr old. He had Dpt vaccination 10 days ago but he has swelling on his left thigh. Is swelling normal in Dpt vaccine? How many days will it take for swelling to be normal?

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 not causing any pain or other symptoms nothing to worry. Swelling can be reduced by giving ice fomentagjytion locally and paracetamol can be given for fever or pain. Thrombophobe ointment can be applied in acute pain and swelling .
