Hello The diagnosis is established and you are having hyper acidity as well other related symptoms like flatulence heaviness in chest . Beside you are also having shoulder pain ( frozen shoulder ) . As you mentioned that in spite of treatment , there is recurrence of symptoms of acidity , so these measures may be useful for you: 1 Try raising the head of your bed about 4 inches with blocks.It also might help to avoid eating or drinking for 2-3 hours before you lie down. To help control the stomach acid one should not drink alcohol or drinks with caffeine in them ( like excessive tea or coffee ) or eat chocolates or greasy food or pizza , burger . When such patient visit I prescribe them to take itopride + rabeprazole combination twice in day on empty stomach for 3- months or till complete cure . 2 Over eating is the second most common cause of hyper acidity , so avoid this when eating food . 3 Tension and anxiety are another most common causes of such symptoms so be careful about that also. As you mentioned that you are having chest pain so please get in ECHO to rule out any heart involvement . For shoulder joint ,consult an orthopedic surgeon . Hope this will be useful for you.
