Hey guys I'm not looking for a diagnosis here, but I kind of need advice as to what I should do next. I have been down with fever since last Friday and I have been like shivering with cold at times followed by sweating. I've seen my doctor twice about this and I was prescribed some fever medication which I have taken every 4 hours as instructed. My body temperature has always been measured at 37.3 degrees Celsus lowest and 39.3 highest. Most of the time when I feel chilly it'll be around 38.5 degrees Celsius, but it'll later drop the 37.4 degrees when I have taken the medication. I don't know whether this is expected of a normal fever but my doctor did recommend a blood test for me tomorrow, which is about less than a week after the fever outbreak started. She said it may be dengue or something known as chiku fever (not sure if I got it right). Is this too soon or should I follow her advice?
