Hi, I am a 28 years old healthy female. Around 9pm on Saturday night I started feeling nauseous and by 4am I was with a 102 degrees fever, headache, extreme body ache and joints pain. I woke up next day feeling the same and my husband took me to the doctor and they told me that I have just a flu. ???? The flu test was negative. Do you think it is a flu or something else??
