today my 9 month old baby got a pcv vaccination, after 4 hrs baby not able to sit without support and can not stand properly. he stands on the toe of right leg. with fever. is it normal or any problem

A. Hello my dear parent! I remember my son had a similar issue after the vaccination. Doctor had advised to give a cold compress or a warm compress depending on the weather condition around. This reduces the pain and the leg can become a little flexible. Paracetamol drops also can help reduce the pain. Consult your doctor for further guidance.
