What causes cough and metallic taste in mouth?

Hi I had a cough in the beginning of the summer. I felt really sick. A few other people I knew were sick as well, while others in my family did not get sick. I continued to have a cough for the last 3 months. I do feel like this is usually allergy related and it feels like an allergy attack. I have never has them like this though. Now when I cough I have a metalic taste in my mouth. Could this be TB, or a lingering infection or asthma(not known to have this)

Thank you for writing in HCM.
Cough persisting for more than 2-3 week is really a matter of concern.
There are many possibilities like
1. It may be due to Gastric regurgitation /acid peptic disorder for which head end of bed to be raised besides treatment of drug like pantoprazole 40mg or similar group drug.

2.It may be a drug induced..more commonly ACE inhibitor gr of drug used for Hypertension or Some other cardiac disease.this mandate change of drug to ARB gr drug.

3.Smokers cough should be kept in mind in Chronic smoker.

4.Cough Variant asthma may cause similar possibitites.easily curable by medicine but need confirmation of diagnosis before treatment.

5.TB is very much common in our country..and easly curable on proper treatment...and for every cough persist more than two week Sputum examination for acid fast bacilli is must in our country.

6.Some serious condition to be rule out like lung cancer by Chest Xray PA view if it is suspected.

So I would like to suggest meet an pulmonologist for proper diagnosis and treatment.

Thanking you.
