The cough that you have described is likely to be an acute exacerbation of COPD
, which can be confirmed from the chest x-ray. Dry cough
is also a side-effect of some anti-hypertensive medications and if you are on any such medication, let your doctor know about it. Please stay in touch with your doctor and he can decide if any further investigations are needed. Do not stop your medications. And above all, please do not worry.
