cervical dystonia operation checkup

Next week I'm going back to Plymouth for them to see how well my operation on 11th Aug 2011 worked, they already told me that I would never be cured, but I do definitely have a much better posture, reduced pain and reasonable left and right movement, I'm really pleased I got the operation, but have already been told that because of the delay in getting the operation, (I was diagnosed with cervical dystonia since February 2009) that some of the bones in my neck have knitted together and so even when I  was completely unconscious in the operating theatre my neck movement to the right was restricted, They will measure the angle of my head and how far I  can turn, then I  have another follow up in three months, then six months, then a year. I  have read that SOMETIMES they need to perform a second operation to get the right muscle's, I  don't think this is likely in my case because they did so many video tests with electrodes in me weeks before the operation, to me, it seems unlikely they got a false positive, but we will see.
