After my lower back fusion surgery, I began to have pain in my thorasic region. Apparently it is very common for lower back surgery patients to get their upper back region a "tad out of whack" because of the changes in and lack of exercise.
My rehab therapist did a snap, crackle, pop on my thorasic region a few times during my rehab. I was hesitant myself, until afterward. I sighed with relief after, and she asked me to get up and walk and see how it felt. I was able to move much freer and then she asked me if I "wanted a smoke"! hahahaha.
I told her it wasn't that good! hahahaha!
If you have been placed in rehab therapy by your doctor and this doctor referred you to THAT particular therapist, the doctor MUST have TRUST in that therapist to do what is necessary for your rehab, otherwise they would not have referred you in the first place.
Just my 2 cents worth. Hope you feel better soon. Tammy
