Hi, I had low fever 99.6 degrees with chills and body ache 4 days back, I took a paracetamol tablet and was ok, then since 2 days I have been having stomach cramps, yesterday evening I again had 99.6 fever with chills and body ache, for which I took paracetamol. What could be causing these symptoms? Do I need to get any tests done. I am a 38 year old male living in India.
