I think a lot of people just think that once the nerve fires, it's game on. I had a pinched nerve in my neck for 9 months while I fought with workman's comp (hurt it in an attic fire). Turn my head to the right and my left arm would go numb.
I finally was able to get the surgery done to fuse C4 and C5 and good as new, except nothing had changed. The first month after surgery I was really depressed, absolutely no progress. I wrongly assumed after a few weeks I would start seeing improvement but it wasn't like that. There was never any day to day progress or even week to week, but after a couple of months looking back I could see that I had made some progress. It seemed like more of a month to month thing for the nerve to heal after being pinched for so long. It took about 8 months for the numbness to go totally away.
My point being is I don't think he woke up one day and the nerve was firing. I think it has been so gradual that you can't even describe your progress. Listening to him and a couple of reports I think he has made progress and it has been enough time for him to look back and clearly see he is progressing. It's frustrating really because everybody that sees you wants to know how you are progressing and you really can't see it on a day to day basis.
I know we had different injuries but nerves don't respond the same way other body parts do. Everything I have heard really sounds encouraging and I think people inside the organization believe he will play this year, but it's not going to be a foregone conclusion. I do believe the nerve is firing to an extent.
