Hello Oakleaf-Girl23!
What is your log in name: Lexus
What has caused you the most pain: Left sacroiliac (SI) joint, lower back and left lower ribs. Though, my left knee and hip, and right ankle are starting to get in on the action lately.
How long have you has AS: Was finally disagnosed Aug. 31st, 2006, after having bum and back and rib pain for four (seems like longggggggg) years.
Where did you start to fuse first: So far (knock on wood), I haven't fused yet, but some damage has begun to occur in my left SI joint, and I think that my rib cage is starting to have some degree of damage as well (lung expansion has so far been a bit compromised on my last physio visit).
How old were you when you first started getting symptoms: My lower back spasmed so hard the day after my 25th birthday that I could barely walk for two weeks after that first "flare-up" attack. Am currently now 30 years old.
Please give your dad a big hug for me, and tell him one more person thinks the world of him as well! Thanks for doing your assignment on this topic...we all really appreciate it! I hope that it goes well for you!

Lexus
