Hello, I am Dr. Romain Rajan, General Physician.
Your case has been allotted to me.
I understand your concern. Having a low-grade fever every afternoon for several weeks can be frustrating, especially when all basic reports appear normal. Since your fever is mild (around 99.5°F), occurs only at a particular time of day, and is associated with body ache and restlessness, it is likely due to chronic low-grade inflammation, post-viral fatigue, or sometimes temperature regulation changes after procedures or prolonged stress.
Regarding your ASD (Atrial Septal Defect) device, infection related to the implant (called endocarditis) is rare but possible in some cases. Usually, if there were an infection around the heart or device, your testsâparticularly CBC (raised WBC count), ESR/
CRP (inflammatory markers), or blood culturesâwould show clear abnormalities, and fever would typically be higher (101â103°F) with symptoms like chills, weight loss, or fatigue. Since your blood tests are normal and the fever remains mild, the device is unlikely to be the cause.
1. Advices
Continue monitoring temperature at the same time daily for the next 5 days and maintain a log.
Stay well hydrated and avoid overexertion; mild fever can worsen with stress, late nights, or lack of rest.
Include nutritious, protein-rich meals and moderate physical activity or short walks daily.
2. What to Monitor
Any rise of temperature above 100.5°F.
Appearance of new symptomsâfatigue, breathlessness, cough, or palpitations.
3. Management
You may take Paracetamol 650 mg only when fever crosses 100°F or you feel body pain.
If this pattern continues beyond 2 more weeks, a few specific tests can help pinpoint the cause:
⢠ESR, CRP, Blood Culture (for hidden infection)
⢠Chest X-ray and Echocardiography (to check heart and device area)
â¢
Thyroid profile and
Liver function test (for metabolic causes)
Often, mild Pyrexia of Unknown Origin (PUO) resolves with supportive care once stress, sleep, and nutrition are corrected.
4. When to Consult a Doctor Immediately
Fever rises above 101°F or persists day and night.
You notice weight loss, night sweats, or palpitations.
New onset of chest pain or breathlessness.
Every patientâs situation is unique. Since your reports are normal and the fever pattern is consistent but mild, this appears more functional or post-inflammatory than cardiac. However, a review with your cardiologist once would be worthwhile to rule out any remote device-related inflammation.
