Hello Sir, Mom (55 years )had the GERD problem ( heartburn ) at the start of last year(Jan),after the advice of general physician she took Mucaine Gel and Cyra D tablets for couple of months,no spicy foods..She was then fine till July/August.Then suddenly she started with dry cough,which she gets atleast once in two days,mostly in the early morning,sometimes late evening.We took the same course of medicine again,but cough didn t stop.sometimes breathing problem, suffocation when she inhales dust,perfume smell.She feels something very sticky in her throat which doesn t come out.If she tries to spit out some white mucus like things come out but very little.Doc diagnosed she has sinus (with X ray confirmation) too,Even after medication for this,still her problem continues.Did a MHC,everything is fine.She still takes Mucaine gel.No spicy foods,No coffee/tea,only milk/horlicks,takes dinner couple of hours before going to bed,no curd (becuase of sinus). But cough still exist,because of cough her heartburn/chest pain goes worse. Any suggestion?Is endoscopy required.Please advise me.
