Antral erosions. To take this medicine?

Hello. I am suffering from antral erosion for past one and half year. I got checkup from AIG hyderabad and took treatment. Later after few months my endoscopy showed platulus ge junction and my complaints are also reduced. But, for past one week again I am having same types of complaints such as indigestion, bloating, heaviness after meal, and stomach pain and also I am feeling some chest tightness. So, I consulted local doctor. He gave me meftal spas, sucralfate, and lactobacillus. Meftal is A NSAIDs drug, is it good to take this medicine? If no please let me know another drug in place of this. Because I am having chest tightness, that I am feeling uncomfortable to sleep at night. So kindly give me a suggestion and how to get rid from this condition.
