Cognitive therapy does not have much of a successful track record. It appears to be recommended by those who profit from it.

Besides the pain, what symptoms are you seeking recovery from?

Your symptoms are a classic combination of whiplash and concussion. The upper back pain and such need a better physiotherapist.

Most therapists are constantly pushing for range of motion. There are some who use myofacial release to help the muscles and joints settle down to heal.

Have they been instructing you to ice the injured areas?

Your brain needs quiet rest. There are no other treatments that promote brain recovery. You can help it with good brain nutrition. My suggestions are posted in Patty's thread "Hello, New Here" Scroll down to my second post.
