I think it did help and feels like it’s tracking better which is huge. I think the nerves need to heal as it’s been out for a long time. Years ago I had a posture bra and I can see if I can find it again. I tried to pop my shoulder back into place with a similar move squeezing the elbows together and it felt good and popped a little but it didn’t help really. ah well..
Chiropractors aren’t detecting these things which is disappointing. It is what they do after all.
