Hey there,
When my right SI was in flare, I had similar issue. Entire SI felt like a ball of inflamation and got so painful, a wrong step could send me to floor as any weight was unbearable.
At this period I really had to watch several items and how i did them.
- I had to climb stairs one at a time and always lead with left leg... going right leg first put too much pressure on SI and caused inflamation to flare more
- could not sit in many chairs... had to have a flat surface.. anything beveled pinched in on my hips and led to inflamation
- worst was sleeping at night.. could only sleep on left hand side or sitting in chair. I usually had to alternate between sleeping in bed on left hand side and in chair.
Fortunately SI has cleared up with diet or when I was on azulfadine. Nothing else ever even touched the pain.
Thanks,
Tim
