I always feel feverish

I have been feeling feverish for the past three weeks. Each time I carried out any laboratory tests, the result will come out negative for malaria and typhoid fevers. I don’t know what else to do. Please help me.

When the causes of a fever are unknown, a lot of investigations are usually necessary to unravel the mystery. Apart from a thorough physical examination by your doctor, a lot of laboratory investigations ranging from blood, urine to stool tests among others are usually necessary.

It is also important to check some of your current medications since some of them can also cause fever especially when they are used in combinations.
