Alright gang so I'm in my commercial (normie, soccer-mom, old-dude etc) gym putting some work in on the heavy bag. Now, the "boxing area" is located next to all the 1lb, 2lb dumbbells and yoga mats... So you can imagine some of the very nice views that are to be had during my workout some of the time. (Not that I'd ever notice, being in my near inhuman state of heightened concentration.) Anyway, I'm going through my bag routine and get to the round I like to call "gone fishin'". Basically this round is all about throwing out hooks for those who aren't quite as quick on the uptake as others (maybe some guys from the UFC board are browsing for instance (Hi!) ). So i throw a loose but hard right hook off the hip, imagining myself landing right under the guard of some schmuck defending his head too enthusiastically. I must have caught it funny or right on a nerve because as I followed through I felt immediate pins and needles shoot up my arm. The sensation quickly stopped but I ended the workout there because spooky. Then, walking back to the changing rooms I had that feeling at the back of my right-sided jaw you get when you catch a good one and the cartilage or w/e is all jumbled about and needs to click back in. Also my two big toes had the same sensation of pins and needles!? Very strange. I feel fine and I drove home alright, but just wondering wtf I possibly did? Google isn't giving me the answers!!!
