This has been my achilles heel for about 4-5 months. From First of February til mid May, I pretty much had this exact same issue every day. It always went away when I went to bed, and would start up an hour or so after I woke up and would be on and off throughout the day. Maybe a few times I went 3-4 days with nothing, but it came back.Then mid May it went away. Out of nowhere, gone. So for about 10 days I lived it up! Then I got over confident and started drinking coffee everyday again, and 4 days later, the pain came back. I felt completely defeated. I have finally begun to rebound a bit, and am praying I am heading back to recovery. I found that the pain always disappears when I take Beano before every meal. Cut back on foods that make me gassy. Relax and not get anxious and avoid ALL caffeine products(I am a coffee addict, so this has been killer) I will try coffee again in August or September if I can get through all of July with no issues. That is my goal.Anyway, yes, PLENTY of us here with left side abdominal pain. Some have it 24/7, some like me have it sporadic throughout the day, others every blue moon. It seems to be pretty common with IBS.
