First off: I am soooooo sad you've had to become a pro at managing your RSI. It sucks when your body can't do what you want it to do
On the other hand, I'm thrilled to hear you're taking care of yourself, Angie! It's so sweet of you to check in on us (even if you're not posting) and even to give a little progress update. Fashion isn't fun when your arm hurts, so please take all the time you need for a full recovery!
I typically don't take painkillers either, but you might consider anti-inflammatories as a supplement to your icing when the cycle begins (ie, when the pain initially hits -- not now, and certainly not after 2-3 days). Since RSI is damage caused by swelling, if you can get the swelling down before too much damage is done, you can lessen the amount of work your body's natural healing systems need to do ... and therefore bounce back faster.
