Hi Crinkle,

An ESR of 20 is normal. I just had a Google (I don't know off the top of my head a normal ESR level!) and it is from 0-22 for men and 0-29 for women, apparently.

I too have Sacroiliitis. I was diagnosed this year after a long history of (strangely) pain in my hips when sleeping which kept me awake, and lower back pain. I had an x-ray and was told it was that and was referred for physio. The physio also told me that I have a lumbar spine abnormailty (sacralisation) which is why I had such a stiff back and the pain.

The physio helped hugely and they gave me some exercises to do at home, which strengthen the core, so less stress is put on the lumbar area and things should not feel so painful.

Apart from the exercises and bog standard stuff like painkillers, that was that. xxx
