A few years back I had quite serious heartburn and went to see the doctor. I was given meditation for a month and the situation ease off and on and off. The doctor suspect I may have some heart problem and refer me to the heart specialist and I told him that my chest keep burning on and off. My heart problem was diagnosed and it was found to be ok. During the process of seeing the doctor I was given medication and the medicine package have words such as duodenal. Since taking that medicine my problems have completely eased off. It has been more about 5 - 6 years and now although I do not have such frequent serious hard burn, my bowel stools are very very dark brown and sticky and stomach bloated. I keep on farting every now and then. It is causing a great embarassment as I seem to fart even after a few seconds or minutes. I have tried taking actal and actal plus but it it only temporary and the situation is still the same with bloated stomach and dark brown sticky stool. Your advice is very much appreciated. Thank you. Best regards from Steven Yong.
