Severe asthma needs regular control with prescribed inhalers (usually a steroid + bronchodilator), not just relief medicines. Avoid triggers like dust, smoke, cold air, and infections, and use a spacer for better inhaler effect. Always keep a rescue inhaler handy for sudden breathlessness, and if symptoms are frequent, worsening, or disturb sleep, consult your doctor to adjust long-term treatment and prevent attacks.

A dry cough with congestion and throat pain for 4 days is usually due to a viral upper respiratory infection or throat irritation like pharyngitis. Take steam inhalation, drink warm fluids, do salt-water gargles, and rest well; you can use paracetamol for pain or fever if needed. Avoid cold foods, dust, and smoke. If symptoms persist beyond a week, worsen, or you develop high fever or breathing difficulty, consult a doctor.

Your symptoms suggest a flare of chronic bronchitis or underlying asthma, and the fact that you still have breathlessness despite repeated inhaler use is concerning. This could mean a severe exacerbation that needs urgent medical care, please seek a doctor or hospital immediately. Until then, stay upright, continue your prescribed rescue inhaler as directed (don?t overuse), avoid cold air and dust, and try steam inhalation, but do not delay medical evaluation as you may need nebulization, steroids, or oxygen support.

For a sputum-producing cough in chronic obstructive pulmonary disease, continue your regular inhalers (bronchodilators/inhaled steroids) as prescribed, and use steam inhalation and good hydration to help loosen mucus; doctors may add mucolytics to clear phlegm. If there is increased sputum, change in color, fever, or worsening breathlessness, you may need antibiotics or oral steroids under medical guidance. Avoid smoking, dust, and cold air, and seek medical review if symptoms worsen or do not improve.
