Possibly, but what I'm really feeling, and it is very pronounced, is that my left arm just cannot coordinate the movements. In fact, when I was first learning how to swim about 4-5 months ago, I realized that my left arm wasn't doing a stroke at all. It has improved through simple awareness, but is still a problem for me.
