Well it wasn't appendicitis, which is good in one way, but worse in another. The scan last month showed the appendix was good, and by process of elimination it's an abdominal strain. So I haven't run since then, and probably won't for several more weeks. An operation and recovery would have been cut and dry (no pun intended). Now I have to wait for the strain to heal and then hope to not hurt it again.
Today I went for a walk of 2 miles, the first real exercise I've had since the middle of last month. I'll know tomorrow if even that was too much. I have done nothing in the past four weeks or so. Before Thanksgiving I bought some KT tape to help shore up the area. It seems to have helped to some degree. Whether that's actually physical or more mental is open to debate. On the mental side it's helped me remember to not do anything too crazy. I know I have more time to go, though, since last week in Austin I ran a couple of steps to catch an elevator at the hotel, and felt a tweak. I don't think I injured it any further, but it was a reminder that it's still tender.
This is not how I'd hoped to end my running year.
