I've been recording how each arm feels on a scale of 0 to 10 (0 being perfect, 1 an acceptable level of mild soreness, 3 and above concerning, 10 being shark attack) since the end of January (which was pretty dumb since I should have been doing this the whole time) and thus after taking the averages I now have a rough idea of monthly progress.
Note that this isn't an accurate measure of how the right arm compares to the left since the right arm is nearly constantly at rest and left arm constantly in use (unless I'm very careful it is still very easy to set the right arm off).
L R
February 3.1 4.1
March 2.4 3.2
April 2.2 2.9
So April was a slightly better month than March (actually the difference between February and March was a bit better than I originally thought).
(Although if you want to get technical, these should be rounded to the whole number since I only have one significant digit in my data... But this looks better!)
For May I'm going to tentatively add another 30 minute or so drawing session for each hand, bringing the weekly total up to 3 hours. We'll see how it goes!
July 1 is my six month checkpoint. If I continue to see improvement these next two months I will continue taking it easy. However if I don't see improvement, then enough is enough and I'm going to start getting back in the game pain or not.
