[|Human|] I have been coughing for the past several months. I went to my internist and she believed that my condition was allergy related and prescribed some over the counter medication. Now, after about eight (8) months my cough is still persistent and I am experiencing a metal taste in my mouth.
[|AI|]  Hello, Welcome to Chat Doctor, As you are taking medicine over the counter, I may not be able to know which medications you are on, As you are having cough for last 8 months you should be evaluated properly to find the root cause of your symptom. It may be allergic also, but we cannot rule out other cause of chronic cough. With this medical history it is difficult to tell what exactly causing the cough. I would suggest you to undergo Chest X-ray, Sputum examination and blood examination. Hope you got the answer for your query. Thank you.
