You may not have a true fever if your thermometer shows 98.3°F (normal). Your symptoms—body aches, mild right abdominal pain, and a small lymph node (7.5 mm)—could be due to infection, inflammation, or other causes.
Advice:
Monitor for actual fever, night sweats, or increasing lymph node size.
Get blood tests (CBC,
liver/
kidney function) and ultrasound if abdominal pain persists.
See a doctor to rule out infections or other causes.
Do not self-medicate with antibiotics without evaluation.
