For a common cold and headache, you can take paracetamol or ibuprofen to relieve the headache and any mild body aches. If you also have a stuffy or runny nose, a generic antihistamine or a saline nasal spray can provide relief. Please make sure to drink plenty of fluids and get adequate rest, as these symptoms are very common and typically resolve on their own within a week. If your symptoms worsen, do not improve after ten days, or if you develop a high fever, please consult a doctor for a personalised evaluation.

For nasal congestion and a dry cold, an oral decongestant like pseudoephedrine or phenylephrine can help reduce swelling in your nasal passages. Alternatively, a nasal decongestant spray like oxymetazoline provides quick relief, but do not use it for more than 3 consecutive days to avoid rebound congestion. Using a saline nasal spray or a humidifier can also safely moisten dry nasal passages. Please consult a healthcare provider before starting these medicines, especially if you have high blood pressure. Seek immediate medical care if your breathing difficulty worsens.

A cold lasting for 6 to 7 days is commonly caused by viral infection, allergy, sinus irritation, weather changes, or pollution exposure. Symptoms such as blocked nose, sneezing, throat irritation, cough, mucus, and body heaviness may continue if the airways remain inflamed or if rest and hydration are inadequate. Dust, smoke, cold drinks, and sudden temperature changes may further worsen the irritation and delay recovery. Warm fluids, steam inhalation, saltwater gargles, and proper rest may help reduce congestion and throat discomfort gradually. Drinking enough water and eating light, nutritious meals may also support faster recovery. Avoid smoking, alcohol, oily foods, and repeated exposure to dust or pollution because these may keep the nasal passages irritated. If the symptoms are due to allergy or sinus congestion, the cold may continue despite temporary relief. Thick mucus, facial heaviness, or worsening headache may suggest sinus involvement. Avoid starting repeated courses of antibiotics without proper medical advice because many colds are viral and improve mainly with supportive care. Consult a doctor if high fever, breathing difficulty, chest pain, ear pain, or worsening symptoms continue beyond several more days.
