Hi. Thanks for your query. Noted the history and understood your concerns. 6 years is a long time to suffer from gastric problems; the fullness of stomach, inability to sit comfortably, palpitation all indicate the need for proper clinical evaluation as you have already taken Famotidine, Unienzyme, Pantop without any use. Get an X-ray of abdomen in standing position. Ultrasonography of whole abdomen. Tests of blood, stool and urine. Upper GI Endoscopy and CT scan of abdomen. All these together will help to get a proper diagnosis so that a proper management can be done. Continue Telma 40. Consult a Gastroenterologist as this will give you the best clinical diagnosis supported by proper investigations to get an appropriate course of management. it seems that anxiety and/or stress has more impact hence should be controlled well.
