I am 18 years old. Last 20 day's ago, I am suffering from fever my physician suggest me some blood test like cbc, widal ,urine test and bilirubin all the reports are normal. But there's little bit infection in my urine, after taking antibiotics my fever is not gone almost 7 days. After 8 days my physician suggest me for crp test and chest x-ray. My x ray is normal but crp is high 17.20 after taking medicine my fever is gone but now after 20 days my fever come back.
