Hello,I thought I would ask a question regarding pain. I seem to have pain all the time, inmy left lower abdomen. It doesn't really get worse after I eat, it's just there all the time. My back is also aching... and of course I have a lot of gas... buildup. Any thoughts? I just was curious if anyone had this nagging, dull pain. I've been to my ob-gyn... had ultrasound which showed nothing, and had a flexible sigmoidoscopy which also showed nothing. I just wanna make sure it really is IBS.thanks!
