have you done gastroscopy？ are you sure you don't have digestive ulcer? Esophagitis？Gastroesophageal reflux？
I think your blood pressure is oK, runing around normal level. you should find out the reason of stomach pain. if you can't have a gastroscopy,you could try some Proton pump inhibitor，like Omeprazole. see if it can make you feel better.
mostly , you should listen to your doctor.
