Can heartburn cause a lot of gas pains that radiate into shoulders? Belching seems to help. Pain worse at night. Started 3 days ago...awakens me approx 2:30am & sit the rest of the night on the couch. Started otc zantac 150mg daily, using tums prn, trialed simethicone but no relief.Just purchased gaviscon & alka seltzer tonight to trial. All started with a meal (spicy sausage, onions, green peppers, cabbage, potatoes on the grill). Bowels move daily. I am a 48 year old female with no health history. Wt wnl. Cholesterol wnl. Non-smoker. Very active. Have had ekg in the last year....nsr. Pulse rate ranges mid 70 s... I have a fitbit on which monitors. Not on any routine medications...This happened approx 1 mo ago as well and lasted approx 5 days (after eating onion rings). I am thinking I continue the zantac routine, avoid culprit foods, drinks and see how it goes?
