My mother started to develop fever 4 days ago. Initially it was 100-101 and then she had Dolo 650mg. But now from the 3rd day onwards and today is 4th day her body temperature isn't going down below 99.3 °F even after taking Dolo for 3 times in a day. She isn't having any other symptoms. Only a bit cough and nose block. Taste and smell are still intact and no extreme fatigue or muscle pain. She's 88kg and 5'4" and already has Thyroid for which she has an ongoing medication. She's vaccinated already with 1 dose. So is that the normal body temperature some people may have or should I consider it as fever? Moreover is it viral fever or covid but the symptoms are less because of vaccine? Do I need to worry for temperature of 99.3?
