I agree with Neurochic here. It appears that you are getting better. Take a breath.

Do NOT have that block done; there are significant risks that go along with that procedure. In my humble opinion, there is nothing that needs to be done (other than what you are doing with range of motion, reasonable movement, etc.) as long as you are making progress.

I think you need to step back and see how things go. Stay the course. With some luck and some time, your symptoms may all go away. No reason to panic or seek yet other opinions which may even further muddy the waters. Remember what I posted earlier about "paralysis by analysis". It is easy to get into that mindset.

Good luck to you. Most of the rest of us would be on cloud nine to be in your shoes!
