Thanks everyone. I'm feeling a lot more positive about this and I'm now confident that the problem will be resolved. I went throught a short phase of minor panic about having to scale down my cycling or worse. The brain imploded just a bit as I've never had to deal with any major injuries despite having done one sport or another for much of my life. I'm also hardly ever ill. I guess this reminded me that I'm not getting any younger and I'm not as resilient as I used to be.
