I am suffering from frequent nauseatic feeling, burping, bloating, lot of stomach sound and constipation since 3-4 months. It is not getting cured by PPI. Have done all blood tests and ultrasound too, which came normal. Now i am also getting tingling in my hands and foot. Feeling very energy less. Could it be a symptom of peptic ulcer? I am thinking of getting an endoscopy done. Stomach has become very tight and there is a lot of gas inside it which is not coming out.
