These symptoms may be due to these reasons, these include.1 Tuberculosis, diagnosis can be confirmed by blood examination for CBC, ES R, chest x-ray and sputum examination, tuberculin test.2 Urinary tract infection is the 2nd most common cause of such fever. Get in complete urine culture examination.3 Jaundice is another most common cause of such low grade fever. Get in HBase examination for hepatitis. There are so many other reasons of such fever as typhoid fever untreated and resistant cases , chronic infection. I recommend you consult one more physician and get his opinion 2nd . Hope this will help you.
