Urgent severe cough. Wil be obliged

Moms age :59 I was having medication for acidity , severe burping , ibs , dyspepsia , and severe flatulence . Over time the acidity and burping is to a much lesser extent but due to Gerd and severe acid reflux I started developing cough . I also have allergic cold with occasional nose blockage and chest congestion . With these two issues u have been having persistent cough over 3 years . Initially for one year it was only while I ate the fir 1st morsel of food where I would feel choked later it has been consistent .it is very severe in the night as i have cervical spondylitis I do not take a pillow but lately have started using a sift pillow . It is dry continuous cough day and night and persistent leaving my stomach and back hurting . Attached is xray report Plz help. Wil be obliged 🙏
