I've had Carpal Tunnel Syndrome for three years now and in June I had an operation on my hand to release the nerve compression that the carpal tunnel was causing. This is the worst thing that can happen to you when you are a writer I can tell you that, the syndrome makes it virtually impossible to type or write for more than 5 minutes at a stretch and the pain takes away most of your creativity...
I had never even HEARD of fanfiction before BBM, I kind of enjoy it, some of it is really good! I haven't written anything, though, I don't intend to. Which fanfiction have you written, have you got it posted somewhere?
Carpal Tunnel is rough, my brother's girlfriend is a sculptor and had the same surgery a little over a year ago on both wrists. She's doing well now though, back to workng on her art like nothing happened though it took awhile. I hope your healing goes well, I can understand what you mean about the pain taking away your creativity.
I had no intention at all of writing fan fiction and though I've been enjoying reading some of it, i've been a little ashamed of it too... but I gave that up and now I do it anyway. then a little while ago, when i realized I hadn't written anything in months because of some personal issues which are causing serious writer's block, I decided it couldn't hurt to do a little fan fic, I wouldn't take it too seriously and at least I would be writing. I only have one chapter up so far and am working on a second. It's called "That Little Bit of Hope" and it's on brokebackslash. The first chapter's a bit rough, it was just a quick first draft, but I'm enjoying the second and should have it up tonight or tomorrow. You're welcome to check it out! I'll post a link to it on the fan fiction board.
