Hi Dear !! Thanks for your query to HCM . Read and reviewed your query and health concerns. You seems to suffer from-Acute on Chronic Pharyngitis. Recurrent dry cough could come from Viral / bacterial infection, in cases with past history of Chronic Pharyngotonsillitis. Due to chronicity,phelgma produced is minimal or nil, as in your case. The coolness of the inhaled air,is from the blast of comparatively cool air on the inflamed pharyngeal mucosa. Gargling and enough drinking of fluids and enough steam inhalation would resolve this cool feeling.Though the inhaled air is warm, the speed of air hitting the inflamed wall makes it feel more cold,as the inflamed mucosa is stuck with fast moving incoming air flow/blast. No chance of pneumonia and bronchitis in your case.But would suggest for check up and Consults for Second opinion from Physician. X-ray Chest with it would resolve your worry for bronchitis and pneumonia. Other causes- like Acid Reflux with lower Esophagitis,TB granular pharyngitis,dust allergy etc need to be ruled out. Hope this would help you to plan further care of this complex illness of yours.
