Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain in case if you have a cough since 8 weeks along with iron taste in mouth and
chest discomfort and if your chest x ray is clear there is a possibility that you are suffering from
acid reflux in which acid from stomach refluxes back in food pipe and throat and it leads to irritation and tickling of throat and it can initiate cough..
I would suggest you to consult an Otolayngologist and get evaluated and along with a thorough clinical evaluation he can refer you to a Gastroenterologist if acid reflux is suspected..
A Gastroenterologist can advise upper G.I Endoscopy to confirm the cause..
For acid reflux you can be advised to take
proton pump inhibitors like
Omeprazole,antacids like
calcium carbonate, taking light frequent meals, avoiding spicy food and doing moderate exercise..
Drink plenty of water and take more of Yoghurt that is a Probiotic in diet..
Hope this information helps..
Thanks and regards.
