It sounds like you are experiencing symptoms commonly associated with a viral upper respiratory infection, such as a cold or flu. These symptoms—blocked nose, mild body ache, fever, and congestion—often improve with rest, hydration, and over-the-counter remedies.

• You might find relief using an antihistamine like levocetirizine (found in Lecope Tablet), which can help reduce nasal congestion and allergy-like symptoms.
• Monitor your fever and body aches; if the fever persists beyond a few days, worsens, or you develop difficulty breathing, chest pain, or severe weakness, seek medical attention promptly.
• Rest, drink plenty of fluids, and consider using a humidifier to ease nasal congestion.

If symptoms continue or worsen, please consult a general physician or an ear, nose, and throat (ENT) specialist for a thorough evaluation and tailored treatment.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
