I have been diagnosed with a bone infection and recently stopped oral antibiotics. I have been running low grade fevers for about 2 wks now...on and off. In the last 3 days my temp has spiked several times to 101.2  How do I know if its just a viral thing and not the infection?.
Hi I do care for your concern.  Doing a blood test will help to differentiate the bacterial and viral infection.  But being treated for osteomyelitis, It's advisable to check whether the infection is completely cured. If I were your treating doctor then I would advise doing a blood work up with ABCs ESR CRP values and consult your physician to know bacterial or viral. If bacterial then bone workup should be done to check for infection cleared or not. Hope I have answered your doubts, if you have more feel free to ask. Thank you.
