Hello Delam44,
I wish you the best. My mother is about 68 years old and she suffers from the same symptoms as you are. please, if you have found any cure, please help her.
she suffers from excessive belching. Belching breaks out even if she have not eaten for several hours, stomach is almost empty. Before belching starts, there is no pain. Pain in the upper abdomen starts with belching. Belching is very excessive, and with loud sounds. she feels embarrassed if belching start while she is in a crowd.
