What Causes Excessive Gas And Intermittent Abdominal Pain?

Question : Hi, I am a 29 year old male. For about a month or a little longer I have experienced bouts of excessive gas mainly at nights and intermittent abdominal pain. It was not extreme but noticeable usually going away and coming back. At times it woke me up but it wasnt an intense pain or anything just annoying. I occassionally have heart burn but not alot. No fever ever or at all but I think sometimes chills or chills like symptoms occur and generally feel tired and hard to sleep well. I initially had pain over my right middle abdomen on a very noticeable point where if you run your finger over it you feel almost a bump or sensitive point and some discomfort but now that went away and its almost exclusively right next to if not right on the right side of my belly button. I pressed it with my fingers for a few seconds and it just feels tender almost like heavier than my other side. I have had abdominal pain or discomfort before for years but not with so much gas. Initially there was bloating that is less now. No loss of appetite or excessive weight loss or weight gain. I just considered it IBS and it does improve sometimes with better diet and more exercise but I want to rule out anything like appendicitis or something requiring immediate attention. thanks.

Hi thank you for the info. So I just want to make sure that there is no way its appendix related or anything like that because the discomfort is now exclusively in the lower right abdomen not really sharp pain but more tenderness and heavyness as if there is something moving or twitching on the lower right side. Also can the medicines be purchased otc and are there any dietary recommendations, I eat pretty much just fish chicken and vegetables to avoid any stomach problems its helped to a degree. Thank you.

ok thank you. I have some mild nausea at times but none of the other symptoms of fever and lack of appetite so I think thats attributable to the gas. Thank you.
