To help manage your fever and ease body aches, you can take paracetamol or ibuprofen. For a dry, tickly cough, a cough suppressant containing dextromethorphan can help. If you are coughing up mucus, an expectorant like guaifenesin is more suitable. Please focus on getting plenty of rest and staying well-hydrated with water or warm fluids. These symptoms are very common with typical viral infections. However, if you experience any shortness of breath or chest pain, or if your high temperature lasts more than three days, please see a doctor in person for a proper evaluation. Take care and rest well.

Itching that worsens at night can be caused by dry skin, allergies, or conditions like scabies. For temporary relief, you can take an over-the-counter antihistamine like Cetirizine (10 mg) once daily, or a sedating antihistamine like Diphenhydramine (25 mg) at bedtime if the itching keeps you awake. Applying calamine lotion or a fragrance-free moisturizer can also soothe your skin. However, because the itching is widespread and nocturnal, it is crucial to consult a doctor for a proper diagnosis and targeted treatment, rather than self-medicating long-term.

Sinus issues, along with a runny nose, sore throat, body aches, weakness, and dizziness, are common during viral infections, sinus inflammation, seasonal allergies, or the flu. When your nose and sinuses are blocked, you might feel pressure in your head and ears, which can cause dizziness or a heavy feeling. Not sleeping well, not drinking enough fluids, and eating less during an illness can also make you feel weak and tired. Drinking warm fluids, inhaling steam, getting plenty of rest, and staying hydrated can help loosen mucus and soothe your throat. Medicines for congestion, fever, allergies, or infections may be needed, but only take them after checking with your doctor, especially if you have high blood pressure, diabetes, or other health conditions. If you have a high fever, trouble breathing, severe facial pain, ear blockage, vomiting, chest pain, or worsening dizziness, consult your doctor.
