Re: Pain in where torso and leg meet
If you've had sciatic joint pain in the past, in all likelihood you've flared it again. I can tell you from experience, it doesn't take much...and it can take a LONG time to go away again. Once you get rid of the pain again, try to make any increases in activity very, very slowly, and gradually. Use ice or a cold gel pack for pain, 15-20 minutes at a time, round the clock if necessary, being careful not to freeze the skin, of course!
There are only ligaments that hold the SI joints in position, but there are exercises you can do to strengthen that whole area, but again, work very slowly and take on any new exercise or increase very, very gradually. Otherwise, the nerve will flare, and you'll be starting all over again.
Good luck. Hope you'll feel better soon.
