There are many over the counter medicines that can help your child cope with pain and bring down temperatures. Be sure to read all labels and only give the doses that are recommended for their age. If it is the first time your child is taking a particular medicine, look out for any allergy symptoms.
Learn your child’s habits, if you see a pattern develop, for instance if they suddenly experience pain each week when swimming is on, talk to your child to see if the pain is real or if they are just feeling anxious.
Sometimes a placebo will make the pain go away! I had an experience with my daughter where she felt ill at school just after they went back from holidays. In the end I bought some vitamin tablets and told her that they were to help with the sick feeling she got and it magically disappeared!
