Hey!
I am 27 years old and suffer from AS since approximately 7 years.
First of all: Sorry for my english, I am from germany

I have my AS realy good under control just with a diet like the paleo diet. But for me the main problem is gluten. So when I kick gluten (and a lot of milk) out from my nutrition, I dont get inflamations in my iliosacral joints and no pain!
5 years ago, I found this diet for me and since these 5 years I followed it very happy.
But the only thing I couldnt cure was the stiffness in the morning. Every morning i wake up after 5 or 6m hours of sleep and I have to move 20-30 minutes and only after this I can sleep again.
5 years ago the stiffness disapperaed till now. Actually my stiffness in the early morning exists since 1 or 2 months.
I thought, that the stiffness disappeares because of a therapeutic treatment from one of my therapists but yesterday I was at his place and got the same therapy and nothing changed

I will ask him a few questions about that but now i have some questions to you:
1) What causes the stiffness in the morning? Is this inflammation? I couldnt find something about that in the internet, the german speaking sources are not very good I think. Maybe you can answer me this question...
2) What are you doing against stiffness in the morning?
3) Do you have a special diet like my glutenfree/dairyfree diet?
I hope someone can help me, I am looking forward to your answers.
Thank you!
