(Male 25) Gassy bubbling feeling accompanied by cramps and pressure or fullness in the lower abdomen all day, everyday for 2 months. Didnt have insrurance so I went to the ER twice where a had an xray, ct scan, and blood work, all showing nothing.Now have insurance and an appointment with a gastroenterologist but its not for a month. Would another trip to the ER be useful or am I likely not on deaths door and able to wait for the appointment.
