Sometime around mid-March I started to have a little bit of back tightness. It was a pretty dirtbike-race heavy few weeks. The tightness went away, but more slowly.
In April I started to experience some morning stiffness that I would have to stretch out. Now in May, after last Saturday's 113-mile dualsport ride around Sedona, I'm on Day 4 and still have some moderate muscle tightness (you might call it spasm).
So, it seems like the effects of the procedure are on the down-side of wearing off. I'll go back to the doc to see if I want to hit it up again or do something else.
Although short-lived, it sure was a nice few months.
