My husband was diagnosed with IBS about two years ago; his attacks are quite sporadic, but when they do come he is in a lot of pain. It seems like most people's biggest complaint is using the restroom, but his is the severe abdominal pain. Although he does have to use the restroom with urgency during an attack (D). I am just concerned about the pain he is having; he has not been to work one day this week because of it and today he said it seems to be moving up under his ribs. Any input?
