Welcome to CrohnsForum JenSwanner,
I am so sorry you and your husband are going through all of this. I am sure it is difficult for you to see him in such pain. You want to "fix it" but are unable to do so.
Has his doctor given him any pain medication? While opiates are not great for Chronic pain, they may be able to help his acute (short term) pain while he is waiting for the medication to kick in. I am not sure what type of meds he is on so am unsure how to answer that question. Has he had similar problems in the past? Does he have an Abscess that is causing him such pain?
I would definately keep in touch with his doctors and let him know how much pain he is in. If the pain does not quiet down soon it may mean he needs different medication or a different type of treatment, of possibly some stronger pain medications.
You mentioned you are trying to keep his diet mild. One of the mildest things I can think of is bread. However, bread is a big trigger for people with Crohn's Disease. People with Crohn's have a reaction to Yeast. Yeast (in bread and other foods) triggers an [wiki=Inflammation]Inflammatory Reaction[/wiki] in their Gut and actually causes more Inflammation and Pain. Also, seeds, popcorn, and this type of thing that can get "caught" in the GI tract are bad foods as well.
A lot of folks have had luck with different diets out there:
Specific Carbohydrate Diet
Specific Carbohydrate Diet
Diet and Nutrition
[wiki]Low Residue Diet[/wiki]
Safe and Unsafe Foods
[wiki]Paleolithic Diet[/wiki]
[wiki]Total Parenteral Nutrition[/wiki]
I know this is a lot of information.....I hope it helps.
I know you are both going through a difficult time right now. Just know, your husband is very lucky to have your support. As hard as it is, he really needs you right now. Thank you for being there for him.
