It is very common for acetaminophen (Crocin) to temporarily lower your fever and ease pain, only for symptoms to return once it wears off, as it manages symptoms rather than curing the underlying cause. These symptoms often point to a viral infection like the flu, or sometimes a bacterial infection like strep throat. I recommend resting, staying well-hydrated, and consulting a healthcare professional. They can perform a simple throat swab or blood test to find the exact cause and guide your recovery.

Crocin contains paracetamol, which is appropriate for her low fever, headache, and sore throat. She can safely take it up to three times a day, ensuring at least a six-hour gap. For her cough and sore throat, warm saline gargles and steam inhalation can bring quick relief. Please encourage her to rest and drink plenty of fluids to help with her weakness and sleep. Since she is sixty-one and feeling weak, it is best to avoid adding new medications without a doctor's evaluation. If her symptoms persist or worsen, please consult a healthcare professional promptly.

Mild post-vaccination symptoms can occur, and since he is recovering well, there is likely no cause for concern. The first dose of Covishield starts building immunity and provides significant protection against severe illness, though maximum protection is achieved after the second dose. Please continue to monitor his symptoms and oxygen levels. If he remains stable and active, you can be at ease.

Since your fever has returned alongside a new runny nose, it is best to consult a general physician first. They can evaluate whether this is a viral illness?which wouldn't respond to the azithromycin you finished?or if a different treatment is needed. A general physician is perfect for this initial assessment; they will refer you to an ENT specialist only if a specific ear, nose, or throat issue arises. For now, stay well-hydrated, rest, and you may use paracetamol as needed for fever control while waiting to see your doctor.

Since you have already taken Crocin, which contains paracetamol to help with your fever and headache, please avoid taking other paracetamol-containing medications to prevent an overdose. To relieve your runny nose, cough, and cold, try steam inhalation, warm fluid intake, and saline nasal drops. A generic antihistamine like cetirizine can help with the runny nose, but please consult a healthcare professional before starting new medications. Rest as much as possible, and if your symptoms persist or worsen, please see a doctor for a proper evaluation.

It is important to know that both Crocin and Dolo 650 contain the same active ingredient, paracetamol. To protect your liver, please do not take them together or exceed the safe daily limit. Since your fever and body aches have lasted for three days, I recommend consulting a doctor for a proper evaluation to find the underlying cause. For now, please focus on resting and drinking plenty of water to stay hydrated.
