Thanks everyone. I forgor to add that whilst I was trying the NSD, there was no difference to my spinal/hip pain or iritis either. Anyway, I've not dismissed the idea that diet can help in some way, particulary in regard to my bowel problems, just that I'm not convinced that the NSD works for me.

As for my diet, I eat predominately vegan. I been vegetarian for 25 years and only have small amounts of dairy, plenty of fruit and veg etc and vitually no processed food. I don't eat perfectly all the time, but unless I've been particulary bad, I don't notice a big difference in symptoms.

Never heard of adenomyosis, although I do have many of the symptoms (always had painful, heavy periods). Even if I was to have it, my AS hasn't been misdiagnosed. The damage / fusion in my spine is very clear on my x-rays.

So far, a combination of Humira, naproxen (when I'm flaring), maxidex and exercise is keeping me going (and the bowel issues predate the regular use of naproxen).
