Anxiety / Stess after heart attack

Hi had endosopy which proved that they was nothing wrong with my stomach, althougth there was a bit of a scare when they thought they had given me another spasm so i spent a day wired up to an ecg machine and loads of blood tests which proved i had not had a spasm. Does not do much for ones piece of mind, Anyway i have been prescribed Motilium (Domperidone) which at this stage i cant say it has helped much one 10mg tab 15 min before meals, Where certain the gas is being caused by stress as you can imagine its an upwords pressure on the chest centre and pain in the gastric areas around the sternam and when i burp the pain is relived, it is not constant and is worse after drinking water etc and eating have had a morning where i did not eat or drink for endoscopy the burping happend very little. Anyway we shall see what happens. jc
