Hi , my son is five years old and he is suffering from high fever since Saturday evening . my daughter who is 7 and half years was diagnosed with measles 10 days ago. So it is similar to the symptoms that she had .He is suffering from running nose sneezing coughing with constant fever more than 101 . I have been giving him calpol 200 for fever but it only gives relief for some time or sometimes doesn't even seem to work. Please help.
