To echo the others who have responded, I too am sorry you have had to take this journey. My experience has been similar, except my pain (luckily) has been relatively mild - still able to work and do my "activities of daily living." But similar in terms of delay diagnosis, nerve blocks, neurontin etc. I also only recently joined this board.

I started neurontin a month or so ago, and found that coffee in the am has helped a lot with the fogginess at work. I had given up coffee as part of my new years weight loss resolution (Because of the cream, which I don't like coffee without) but started back up after going on the neurontin.

Don't know if this helps you, and some others have said people with RSD/Crps should stay away from caffeine, but I need to be sharper at work, so I am taking the risk. Plus, between the nerve blocks and neurontin, I've been sleeping better lately anyway.
