My son is having fever of 104.8 F since 11th of June 2011. He was admitted in hospital and all the tests are done, but all are found negative. Doctors have put him in Pyrexia of Unknown Origin . His fever comes upto 104.5 two times in 24 hours. We give him Calpol and then fever subsided to 99F within an hour and he becomes normal. But, after around 11 to 13 hours the fever comes up again and rises upto 104.5F. Only medicine now given is - Paracetamol. Please advise what has happened and how it can be cured. He has become very very weak.
Hi, Many a time it is difficult to diagnose a fever case. Rhis is called Pyrex of unknown origin. This indicates that there might be having some infective focus in his body giving continuous fever. You have not mentioned any investigations made to diagnose the condition. He might require,1, x-ray chest,2, complete blood test like TC, DC, ESR, platelet count, Tidal test3, routine and microscopic urine report4, if you require blood culture.4, if you require blood culture,5, ultrasound of abdomen. After all reports your doctor might have some clue about his fever.Meanwhile, give him paracetamol as and when required. Give him enough water and light food. Ok and take care.
