Recurring low-grade fevers with body aches, headaches, and fatigue can be very draining. These symptoms are often caused by a lingering viral infection, but they can also stem from other underlying inflammatory or bacterial conditions. Since antipyretics like paracetamol or ibuprofen only offer temporary relief, it is important to listen to your body. I recommend seeking a medical evaluation if these symptoms persist for more than three to five days, or sooner if they worsen, or if you experience warning signs like shortness of breath, severe neck stiffness, or confusion.

Because your son's fevers are highly predictable, last four days, and are linked to high inflammation markers with no weight loss, this pattern strongly points toward a periodic fever syndrome, like PFAPA. It is very reassuring that he is growing well. While Crocin (paracetamol) and Meftal P (mefenamic acid) help manage his symptoms, I highly recommend consulting a pediatric rheumatologist or immunologist. They can guide you toward specific tests and treatments to help prevent these monthly cycles.

With the prescribed medications?Meftal Forte (mefenamic acid/paracetamol) to manage the fever, Azithrol (azithromycin), and Vitamix?it typically takes 48 to 72 hours for your son's temperature to stabilize. A CRP of 65 indicates active inflammation, which explains why his fever is fluctuating as his body fights the infection. Ensure he gets plenty of rest, stays well-hydrated, and takes his doses as prescribed. If the fluctuating fever persists beyond 3 days, or if he develops new symptoms like breathing difficulties or extreme lethargy, please consult his doctor for a re-evaluation.

Meftal Forte, which contains mefenamic acid and paracetamol, should only be taken when you actually have a fever or pain, rather than on a regular schedule. You can typically take it every 6 to 8 hours as needed, but please do not exceed three tablets in a 24-hour period. It is always best to take this medication after meals to protect your stomach from irritation. If your fever lasts for more than three days or is accompanied by other symptoms, please consult your doctor so we can ensure you are on the right track.

Persistent loose stools and lower abdominal pain after a fever may indicate a lingering infection or gut irritation. You should consult a doctor for evaluation, maintain hydration, and avoid self-medicating until the cause is identified.
