I had a patient present with low back pain.  As I do with all my new patients, I asked him to recall all his previous major injuries as I always clear these first.  Included in his history of injuries was open heart surgery back in 1994.  His left chest had been numb ever since.  I performed IRT to the area.  When he came back in a week he replied that he was now able to feel his chest.  It had been 13 years of numbness in his chest and now he was able to feel again.
