welcome to HCM.
Understanding your concern.
Thanks for your query . The most probable reason for tickly throat and dry cough is acid reflux
disease or gastrointestinal reflux disease (GERD) . In this disease upper sphincter of esophagus allow the acidic content of stomach to come upwards in esophagus , which causes throat irritation
and dry cough.
I would suggest you to avoid spicy and heavy meal, avoid late night eating , eat at least 1- 1.5 hours before going to bed and take frequent and small meals .
Consult gastroentrologist for proper examination . Doctor may order endoscopy test , ambulatory probe tests and X-ray of digestive system.
Doctor may prescribe antacids(gelusil) to neutralize acid . H2 blocker (ranitidine
) to prevent acid production and proton pump
For now follow the above instructions , keep your head elevated while sleeping keep clove in mouth to suppress cough and do warm saline gargles.
Hope your concern has been resolved.
Get Well Soon.
