They put the polio vaccine and the MMR for my son. The day after had fever and headache , one day I was fine. Now her legs hurt and has trouble walking, is it normal?
It is very normal MMR contains tetanus. If you have never put a tetanus injection have pain for 2-4 days after . Headache and fever are normal , the immune system is responding correctly to the vaccine. Take him to the pediatrician to make sure it is not a cellulitis infection .
