So in the meantime, I have been using voice entry a lot (Android rocks at that!) and icing my arms as much as I can stand.
If you are worried, don't be--it's already getting better. I've had this once before, from the same stupid behaviour, and healed myseld in a couple of weeks. Back then, I thought I had learned my lesson, but apparently I needed a reminder.
Anyways. What this means for now, is fewer posts from me while I heal. I'll be back before you know it.
