Hi. I'm having a fever which has lasted for 3 days as of now, it doesn't seems to subside with Paracetamol, temperature is about 37.5 degree Celsius. Besides, I feel very tired and sleepy even though I have just woke up from a nap. The doctor has took some blood for Full Blood Count test, but the result is not out yet. Is it necessarily to go to the hospital, or what should I do? Please help.
