A textbook case
A new female client in her 60's came in. She had very bad "sciatica". Went to see a chiropractor. He massaged her back and it almost got worse so she came in to see me 2 days after.

Screening directed to her right TMJ. I released her TMJ (sphenoid) then turn her over.
Right glutes were still tight and kidney was warm. I asked if she was stressed or not sleeping, said she had been extremely stressed.
After Kidney move, it cooled down and low back released 80% after piriformis, and Sacroilliac joint move and hamstrings move. One week later, she came back and reported her back has been lot better.
