Yes I had it done a few times, worked out great for me- it was like a miracle!. and so painless and simple.
I was just amazed.
You might have over done it enjoying the good feeling.
Easy to do that.

Mine tried to raise up again a few times after that first drop down, but I told my chiro about what the adv. PT guy did to relieve that stubborn problem and he started checking it each time.
He uses a different technique but it works also.

I can now tell when I'm getting into that "tension" zone in and around my collar bone/shoulder junction -and can usually stop what might be triggering that tension before I go into spasms or ending up with the top ribs stuck again.
