You are obviously well-read and up to date with your disease.
There are few things of significance:
Whilst Crohn's disease may cause joint complications, those without Crohns also get joint pain. It's possible that your spinal pain has nothing whatever to do with your Crohn's.
I don't agree that patients with inflammatory disease should not be treated with manipulations. I've successfully treated numerous ankylosing spondylitis patients for lower back pain. But obviously with care, more gently... exercise is a vital part of the management. Done daily before getting out of bed. See our lower back exercise programme at C-H.
Simply because you have neck and back pain, with no confirmatory tests that it's axial arthritis, it's non-sensical to say you should not be treated by a chiropractor. Having said that, with care, with interaction, someone you "click" with.
Some people get relief, even complete relief, by avoiding all gluten. That means no bread at all, suggest you talk to a dietician.
As with all arthritis a change to more vegetable protein is vital. Start with making hummus (type hummus into the Search this site function at C-H). It's very easy to make at home. Then more tofu, fish... lentils, beans. However, changes in fibre in your diet should be done cautiously and in small amounts, finding what you can tolerate.
Start taking extra omega-3 oil and eating foods rich in omega-3, particularly fish and flaxseed. Use the latter in your hummus. These seeds must be ground, or liquidised with olive oil.
Reduce your omega-6 which means a move from seed oils like sunflower to olive oil.
Start looking for a chiro in Durban who is experienced, has an interest in nutrition and exercise.
Good luck, I hope this has contributed.
One last thought: fasting. It has a place in the management of Crohn's and AS.
