Kindly review my test reports and confirm if I have an infection or autoimmune disease?

Hello doctor,

Over the past year, I have had polyclonal B cell activation, raised IgM, and positive ANA (antinuclear antibodies) with systemic flu-like symptoms. However, doctors do not comment on anything because I have worsening symptoms. I experience fatigue, Raynaud's disease, skin rashes, petechiae, livedo reticularis, episcleritis, awful muscle aches, joint pain, awful headaches, fever, chills, hair loss, mouth ulcers, and light-headedness. Do I have an infection or an autoimmune disease? I have provided the details of my test results:

1. ANA test: Positive six times but negative twice.
2. Complements: Normal.
3. FBC (full blood count): Normal.
4. ESR (erythrocyte sedimentation rate): Normal.
5. C-reactive protein levels: Normal.
6. Liver and kidney function: Normal.
7. Urinalysis test: Leukocytes are present.
8. ELISA (enzyme-linked immunosorbent assay) for Lyme Disease: Positive.
9. Western blot test: Negative.
10. CT abdomen: Swollen spleen.

Hello doctor,

Thank you for the reply. Could ANA levels fluctuate? Also, do you think the ELISA for Lyme disease is relevant, or is it false positive because of the negative western blot test? I have had conflicting opinions about this. My neurologist said it was a false positive. Meanwhile, my rheumatologist could not comment on anything. If it is a false positive Lyme test, could that be caused by autoimmunity?
