Excruciating ibs pain

I have ibs u and the pain lately has just been getting worse and worse I've had about 4 hospital trips because of this the only drug that the hospitals gave me that worked was a very addictive and dangerous drug which I can't have again until I'm older morphine had no effect and I'm in so much pain constantly that I'm screaming and crying in pain , I can't move , can't eat and can barley drink but the doctors I go to can't really do anything they said they've never seen such a bad case of ibs in their career and I was wondering what you all take to help with ibs pain
