I am having severe cough from last 3 months. X-ray , blood report, thyroid levels everything is normal. 10 days back i met a ENT specialist and he gave me some medicines which relieved me. The medicines were for 1 week, only Mondeslor have to be taken for 20 days. After finishing the dose for 7 days, from last 3 days my cough started again, though not so severe but still its high. suggest me please.
