After my first session Bowen gave me great relief, but it was just for a few days. Why did my body go back to where it was?

Because your body received relief I say, “GREAT we are on the right track and Bowen will do you well in your case!” Your body is used to being in the pain/spasm cycle and the brain is used to keeping it there. Re-patterning the brain and body through just a few more sessions should do the trick for you. Practitioners see this re-patterning happen all the time.
