Hernia and Ab exercise??

I have a rather large insisional hernia in my belly. I've been doing abdominal exercises and I was wondering if these are hurting or helping my hernia? Should i stop?

If it hurts don't do it. I just had 2 incisional hernia's repaired. I could still do hanging leg raises and stuff like that with the hernia, but 1 crunch and I'd be doubled over in pain and pushing the sucker in. I seemed to be able to do decline situps if I didn't push the reps to the limit too. Exercises that simulate that crunch too, like deadlifts (big time ab exercise btw) would lead to a lot of pain and suffering. Earl
