I know that AS is commonly associated with morning stiffness and improvement with movement. I actually find that I feel better in the mornings, and then after several hours sitting at my desk and moving around the office that I start to get some pains in the afternoon and evening.

Anyone else share this pattern?

With A.S. anything is possible. Sorry that is no help to you but with A.S. sometimes that's just the way of it.

Have similar experience. But in my case I had the morning stiffness, than improvement with movement and than some pain in the late afternoon and evening. I felt better in the morning than in the evening.

My stiffness goes away with movement. In the morning I get up and move around. Most of the day I'm moving periodically. When I sit down to dinner, though I linger for half an hour or more enjoying my family and when I get up I waddle for a few minutes. They think it's funny (I have a 10 year old boy - all bodily functions are funny). So, for me...the stiffness returns after a period of inactivity.

Sounds a bit like me

I changed my chair at work several times before things got better

I have found how I sit and what I sit on even if briefly can make my pain or stiffness increase quickly

I will alternate sitting and standing at my desk also to find the right balance

Stiffness always worse in the morning when my AS presented more issues.. if i slept wrong, it could make so much pain could not get out of bed easily, would take me several minutes to try and roll out of bed to my hands and knees.

After hot shower and movement got better.. then depending on what I did during day could improve or worsen.

Best to you,

Tim

There were times when laying to sleep hurt, sitting hurt, standing hurt, walking too much hurt....I was stiff and sore when I woke and I was sore and tired by the end of the day.
