<s>[INST] Hi, every so often I will be in a tight situation. For example, recently I was in the middle seat of an airliner. I didnt have much room. I took of a sweater and my upper right ab muscle actually popped out. I am thin and in good shape, lately my stomach has been tight but bloated and with gurgling sounds and occasion burning in the stomach area. I am 53 yrs old. [/INST] Hello sir,The history you mention looks like if the tissue is herniating from abdomen.And burning sensation could be due to gastritis.Kindly consult an general surgeon for examination and to look for your problem.Thank you. </s>
