I would hate for you to assume that it is a riding problem when it could be something worse, it is probably smarter to go to a Dr and get checked out. The Dr will likely not be familiar with horses, but they will be familiar with exercise in general and can do heart stress tests on a treadmill.
To help your breathing while riding, trot, as you post, count down = breathe out, up = breathe in. Do the same with the strides of any gait, if they are too fast, then do it for two strides. Count to yourself all the time.
Did you get light headed before the pain started? If you were holding your breathe, I would imagine that you would get light headed first.
