[|Human|] Hi, My Dad, aged 62, height 57, weight 70 Kgs is having fever with headache almost every evening from last 30-40 days. Got Blood, Malaria, sugar, urine tests done but all negative.Visited many doctors, but till the time medicine is continued fever is not there but will again come as soon as stopped medicine. And the fever is 100-102 C. First headache will occur followed by high fever but only in evening/night. Recently we saw ENT Specialist and he gave some medicines for throat infection. Now again when he stopped medicines, fever is there 102 C. No clue what to do. Could you suggest something ?
[|AI|]  Hello and welcome to Chat Doctor, Fever rising in the evening specifically is suggestive of tuberculosis. Tuberculosis is chronic infection caused by bacteria Mycobacterium tuberculosis. The fever is accompanied by sweating. Along with fever, there is loss of appetite and weakness also. There can be associated cough with sputum also. I suggest you to consult your primary healthcare provider for clinical assessment and relevant investigations. If sputum is also generated, sputum examination also needs to be done. Thanks and take care Chat Doctor.
