I'm jealous that that was your first fall! By the time I was 15, I'd lost count of how many times I'd come off.
Don't worry, the pain should ease in a few days. If not, make sure you get x-rays. Your back isn't something to be messed with, believe me - my last (well, second last) fall completed stuffed my back, and it's not something you can or should ignore. You probably should get x-rays anyway, and make sure you mention it to your doctor in case anything comes up in the future.
But like the others said, good work for getting back on! And yes, you might find it daunting next time you go to canter, but it will pass. Falling off makes you a better rider, or at least I think so!
