How can you tell if one of your si joints are out of place or stuck?

You will feel pain or discomfort over the SI: Usually it's not dislocated, but oftentimes there can be spasm if it's stuck. If that's the case, you will feel discomfort over the actual sacriiliac joint area in certain types of sitting positions or rotational or twisting positions. It's best to see your osteopathic physician, to have this evaluated fully, and treated, so that you can get out of pain.
