I found a description of what happened to my leg, it's a fairly common injury in people my age and usually referred to as "Tennis Leg". Here is the description of the injury and rehabilitation at about.com. It's pretty much spot on.
Tried taking crutches to work today, it was more of a hassle than simply walking slowly. Got attention though. I'm telling people I got the injury sparring a 3rd Degree Black Belt, which is essentially true. We just weren't making contact at the time. :P
Also found the time (how? where?) to take a few pics with my semi-new refurbished LOMO LC-A, hope this roll turns out better than my last failure with the camera. It's no XA2, you have to read the instructions. DOH!
