A. Hello ma’am See the pain and fever can last for 48 to 72 hours so start applying ice on to that area every 2 to 3 hours so that slowly gradually the pain and swelling will settle down and keep giving paracetamol to your child every eight hours if there is too much of a pain because that way your child will come down and your child will be able to sleep and walk after that
