Hi, during the last two weeks and a half I have experienced the common symtoms of fever recurrening during the day, yet my temperature seems to be at a constant 36.5° (yes, i ve tried different thermometers). Other symtoms are: hoarse voice, lack of energy, - and a rough chest feels like a lung infection. - I do not have any other symtoms. - Now, during this period I ve taken two sets of antibiotics which have not made much difference. I have also taken a radio of my lungs with a normal result. thank you
