What is the reason why the baby's arm swelled after receiving the DTP vaccine?

Patient's question:

No

Doctor's answer:

Mainly, it is due to the rapid healing of local wound tissue. The main symptoms of wound inflammation are local redness, swelling, heat, and pain. If there are no symptoms mentioned above, it cannot be said that the wound is infected. It is recommended that you apply local heat, physiotherapy, and massage. If necessary, local closed treatment can be used.
