Trail Run #6 - sort of

On Tuesday, my wife and I went out to run the Rexius loop here in Eugene. We'd never run this trail and I was looking for something flatter again, as I still had some knee pain. We headed out on what is a really nicely done trail. It's essentially flat and the shredded wood surface is the softest I've run on to date, and was just awesome, and my knees were feeling great. However, at almost exactly one mile in, my lower back twanged, and bam, I was done. I've had issues with the lower left side of my back, off and on, for a long time. It's residual from a severe cycling accident I had many years ago. I have essentially no feeling in an approximately 6"x6" area of my left low back/butt cheek/hip area, but internally it seems I can pinch a nerve or some such there on occasion. It can be bad enough sometimes that I can barely walk or move much. Sometimes it takes physical therapy and special drugs, other times just a little "Vitamin I" (aka Advil). Anyway, we walked back to the car, which sucked, as this looked like a great run for the day, and I was even on a pretty solid pace. Argh. I've been doing the 3x/day ibuprofen treatment since then, and finally it's a lot better. Yesterday was really bad, as it seemed to cause some serious tightening and pain in my right knee (I believe that's a side effect of what I suspect to be a pinched nerve, as this kind of thing has happened before and that was the supposed diagnosis if I remember correctly). But today I'm feeling much better (plus I feel like all the knee pain is gone too), and expect to head out on my road bike on Friday, and maybe also Saturday. Sunday I'm planning to ride Brice Creek (mtb), then chill for the rest of Father's Day.
