Don't know if I'm too late to jump in here, but I agree with a lot of what's been said: Take a break from photography, go to museums, look at paintings, read, take some good walks, etc. And I'd add to do all of that, but without an end or aim in mind. Plus, draw. Draw with your good hand & draw with your opposite hand. Just play.
When you start shooting again, do the same thing: Just play. No pressure. No expectations.
Whenever I get blocked, I always find that it's stress that's at the root of it. Sometimes the stress creeps up on you in a way that you don't even realize that that's what it is until it's a huge weight around your neck. And with the economy the way it is now, it's sooo easy to put too much pressure on youyrself to make every picture/print count because images are so expensive to produce.
And if all else fails, sometimes you just have to follow the advice (one of my favorite TV quotes of all time), 'Just pull down your pants and slide on the ice.'
