Hello,
Thanks for your query.
Your having pain around chest, arm and back probably due to dyspepsia/
Gastroesophageal reflux disease. In this disease you feel heart burn and
indigestion with
bloating caused by reflux of acid from stomach to
esophagus (due to relaxation of lower esophageal sphincter).
As you are already taking medicine for it but it dose not resolved.
You need to change your life style by avoiding spicy food, carbonated drinks, caffeine, tobacco,alcohol etc.
Do not go to sleep within 2 hours of taking meal.
use extra pillows during sleep to raise your head.
Lose weight if you are obese.
Exercise regularly.
As you are also hypertensive, you need to visit your doctor and get chest x-ray and ECG done to rule out any cardiac problem. You may be advised to get your
endoscopy done as your GERD is not healing with treatment.
Hope it helps,
Take Care!
