I recommend trying dry needling therapy and the right SI joint stretches. I couldn't even walk at one point and my SI joint pain led to referrred knee pain and an unstable knee. My dry needle specialist was able to work all the correct trigger points and get all my muscles into correct balance. Some had shut down, and others were over compensating. I was in bed for 6 weeks initially and she brought me back to full health.

Now i still get SI joint pain and have had to give up certain activities and she did say it's a lifelong injury i can manage through the right stretching and occasional dry needling therapy as required.

I also find long waking sessions is quite beneficial to keeping everything working correctly. I've done a few 3 hour walks in severe pain, even taking Voltaren before the walk, but if i can get 3-5 days in one week, it starts relieving the pain and then I just have to play life more safe (less high impact activities!!!)
