My son is allergatic to dust, seasonal chang e, pollans and was diagnosed with adenoid at the age of 7 yrs but due to proper homepathy he managed well, and no need to do operate.3-4 days back stomach was little upset with no major issues like dehydration or vomiting . He got recovered but suddenly today afternoon he said he is having little temperature , I measured it was 99.5 C under tounge, my two questions are. In kids where we have to measure temp at tounge or under arms ? Upto what temperature we should not give medicine? Why fever comes if everything is ok
