Hey Karen,
I was diagnosed with sciatica when i was around 25, but no xrays or anything done and it was no big deal, exercises and sleeping with pillow under knees and it went away. never any problems except with pregnancies.
Fast forward to 38, started feeling really sick with peripheral joint pain and tendon problems. xrays a year later showed something on my si joint that made my rheum suspect spondylitis despite neg. gene test and no low back. then the pain started, had mri showed unilateral sacroiliitis. The tendon issues seem like a big clue.
If i go by when i really started feeling like crap- a little over a year for evidence, but i'm guessing the sciatica at 25 means somethings been brewing the past 15 years.
Gotta ask how do you realign your SI? I bent down to help my 3 year old yesterday and something happened - felt like a warm jab then hot water balloon bursting in me, the pain's left side (not where mri showed problem) si region radiates around hip and i can't bend over now. been doing ice and heat.
thanks mc
