Did the PT teach you how to put your own SI back in?
It can be incredibly easy to do with the right tricks (if it's actually the SI. Are they sure it isn't your lumbar spine?). I taught Mimi this one, so if you have trouble and my explanations aren't doing it for you, give her a PM and I'm sure she could help.
Your SI may squeak in and out, but it's the muscles freaking out around it that cause the trouble. To solve it you need to both calm down the muscles and let the SI go back where it wants to be. (trust me, it wants to go back!)
Easy Fix:
This is called the "Soft Shotgun", cuz like a shotgun it hits many targets. (there's also a 'hard' shotgun, and I don't use that) Doesn't matter which SI is out, or what direction it wandered off into. This exercise calms down the muscles in the neighborhood and lets the SI's squidgy their way back where they belong. (if the problem is in your lumbar spine, this will likely make you feel worse) I usually tell folks to do this morning and night, in bed, for a couple weeks. And whenever their SI feels funky. As often or as little as you want.
*Lie on your back, knees bent, feet flat on the bed.
*Stick a pillow between your knees.
*BARELY, gently, imperceptibly squeeze the pillow for 10 seconds.
*Let off for 10 seconds
*Do until you are bored silly. (generally you become bored when the SI's have returned and your bod is no longer excited by the gradually shifting SI's) Maybe 10 or 20 or 30 times.
It's like rocking a baby, in that it calms the muscles. Using the in and out muscles of the legs kind of flaps the bones of your pelvis like elephant ears and lets the SI work its way back into place (which it would normally do with every step you take, every move you make, every bond you break etc etc with apologies to Sting)
You might also want to try sleeping with a pillow or towel roll between your knees if you sleep on your side.
If this doesn't work, let me know. I have a few other tricks up my sleeve...
