Goldenlablover....Hubby suffers from Crohns so I empathize. You might consider working in research...check out a medical school if one is near you or a large hospital. Nurses with ICU experience are often required for studies that involve critically ill patients.
Another option is telephonic nursing support, either disease management, triage, education or something like that.
If you don't mind losing the patient contact, you could consider an insurance company nursing job. Nurses there review claims, authorize procedures and other clinical/administrative type jobs. Good luck!
