So we figured out what was wrong with my arm. I tried to train last night and couldn't, but I hung out the whole time and went and beers afterwards as per usual. One of our instructors was talking about how he wants to get some "medical putty" to help him work out the kinks he gets in his fingers occasionally. That reminded me that my dad got me some of those
grip strengthening handle devices for Christmas, and that I was really stoked on them and used them pretty much the rest of Christmas night and most of the next day (Saturday, when my arm started to hurt). So I told him this and he was like "Well dude... there you go.. that's why your arm hurts! You overdid it!" Apparently I enjoyed them too much and that's why my arm hurt up in the shoulder. Weird, yet relieving
My arm feels about 95% today
