I'm a 27-year old female, 5'6, 135 lbs. I've had lower left abdominal pain for about 2-3 months now. At first I didn't think anything of it, I thought it might have been something I was eating/drinking. I stopped drinking soda which seemed to improve my symptoms for a short time. However, the pain returned and now seems to be slightly worse when I do get it. The pain will suddenly come on and usually goes away within a few hours. My symptoms are cramping and bloating. Both my dad and paternal grandfather have diverticulosis and I'm concerned I might have the same symptoms. Could diverticulosis be the cause, or is this something else?
