Well, this is depressing… I apparently sustained some sort of shoulder injury during the aikido seminar last month – not entirely surprising, since the central focus of the seminar was on the many ways to get into sankyo (for those who don’t practice aikido, this is a technique that ends with uke pinned face-down to the mat with their arm twisted behind them perpendicular to the plane of their body). I’ve given and received this hold (and a related hold, nikkyo) many times, but not over and over all day. In typical guy fashion I ignored the (relatively minor) pain for a while, but it kept not getting better, and then the other day I picked up a small pile of books with that arm and it felt like something was separating that shouldn’t… so I finally went to the doctor.
The X-ray revealed a minor degree of osteoarthritis in the shoulder, and I’m scheduled for an MRI next week; for the moment, certainly until she knows the extent of the injury and possibly for some undetermined period after that, I am officially out of training (and right before my next kyu test, naturally). Not sure yet what I’m going to do to keep myself active in the meantime – probably get back on my bike more, as a start, since that doesn’t require much work from the upper body.
