Like the others here, my wife have this mystery fever. It's been about 3 months since she is suffering from fever of 99.7 deg C which is lasting for 2 to 3 hrs in exactly 5 pm in the evening everyday, sometimes headache-twice . Not very much appetite or thirst , no loss of weight. Every day atwo bobble, may be air or i don't know is appearing at her colar bone which disappears after 5 to 10 minutes. She was scanned with doppler neck scan, abdominal ultrasound, all blood tests, FNSC, TB. But no evidence of any desease. Everyday after the fever, she feels extreamly tired and have no strength atall. She had times, when I thought she is finished..., please help, what should we do?
