It all started with fever and chills on feb 5. I took paracetmol and it subsided in couple of days. Again on 3 or 4th day temperature got high. We finally visited GP to know the cause. They ran blood test on feb 14 and another on feb 23. The only thing we saw is crp got high from 9.7(on feb 14) to 34 (on feb 23). We took ct scan of upper chest and stomach and everything was normal. Took x ray of chest and it came normal. What could be the next step to do? Thank you.
