am 56 years old, 5 7 and I weigh 195 lbs, For the last 2 days, I have felt like I have gas trapped in my stomach with a constant lump in my throat that won t go away. I feel like I have to belch and when I do, it helps slightly but then returns to the symptoms above. This is becoming more uncomfortable. Past stomach issues occurred about 10 years ago when an endoscopy discovered parasites. I was put on meds and it seemed to take care of it. Haven t had an problems since, until now. Is there anything I can do on my own to help?
