There are many reasons for a low-grade fever. Obvious sources of infection should be ruled out, including cultures of blood and urine.
A PPD can be planted to exclude TB. Imaging studies of the chest/abdomen/pelvis can be done to exclude an abscess as well as lymphoma.
Accompanying blood tests can be done to help exclude an infection or inflammation. Examples would be a blood count as well as a sedimentation rate.
A referral to an infectious disease specialist should be considered to discuss these options.
Followup with your personal physician is essential.

his symptoms sound like inflammation, but finding the underlying cause of the inflammation is something you need to work on ASAP, even if it means getting another doctor, or at the very least, a second opinion.
In addition to ruling out lupus and lyme disease... I would add Chronic Fatigue Syndrome to the list. Low grade fevers, allergies, muscle aches and flu like symptoms are common in CFS patients'.
Good Luck !
