It might be GERD. You should see a gastroenterologist, but if they suggest to take a PPI, ask to first try rather an H2 Blocker. Meanwhile, you can try to take Gaviscon when you feel the pain and see if it relieves it. You can also try TUMS, but Gaviscon is better. Do deep breathing and stretching and relaxation exercises. Drink and drink - water - for the constipation. Don't drink seltzer/soda (the bloating causes heartburn). Look up other ways to help with diet - chew your food very well and don't eat in a rush, don't slouch. Not digesting the food properly, or eating hard to digest foods can cause heartburn. I've found that popcorn, persimmons, peanuts, sometimes cabbage, give heartburn, especially if you're not able to completely chew properly. Good luck
