I have had a low grade fever for 6 months. the temps vary by day 98.8 - 100. i have had many tests including a ct scan with contrast. symptoms are joint pain, fatigue (off and on), feeling flushed. it is coming back normal. do i worry or accept this?

Autoimmune disease, chronic infection should be considered. A diagnostic workup may include an autoimmune panel, inflammatory markers and CBC, differential, platelets.

Be sure to have a specialist in infectious disease involved in your workup. After this assessment you may he referred to a rheumatologist for more evaluation. In my experience cases of fever of unknown origin are best worked up in a hospital where testing and consultations with other specialists such as rheumatologists, hematologists,oncologists will see the patient also without delay.
