kdefro, Master Lin says that when you experience these physical sensations, be they pleasant or not, that is the best time for healing, so stay with your meditations.
Like Jetay said, it is exciting to increase your awareness of yourself and to experience the movement of qi and know that it is a healing.
I say all of this without every having felt anything like you describe during the small universe. I don't know if I'd say I feel qi as a river, but I find that each cycle of the small universe is calmer, slower, deeper, more relaxing than the previous one. That said, I've experienced movement and even some unpleasant sensations while doing SFQ, but it's all been for my betterment.
You are perfection,
