A dry cough for a few days is often caused by a viral infection, throat irritation, or an allergy. Warm fluids, steam inhalation, and adequate rest may help soothe the throat and reduce coughing. Try to avoid cold drinks, dust, and smoke, which may worsen irritation. Consult a doctor if the cough continues or becomes severe.

Frequent throat infections may occur due to allergy, sinus issues, or reduced immunity, especially if you have asthma and diabetes. Taking antibiotics on your own is not recommended, as they may not be needed every time. Good diabetes control and avoiding dust and irritants may help reduce infections. Consult a doctor to find the exact cause and advise suitable treatment.
