Over the last year, I've been slowly doing more of my own bike maintenance.  It started with a simple chain and cassette swap, moved to partial disassembly when I started travelling with my bike, and recently, I've been replacing cables.

As I gradually do more maintenance, I am acquiring the necessary tools and knowledge.  Some tasks are simple and others require a few tries to get it right but for the most part, everything has gone well.

Over the past couple of weeks, I've been dealing with a nagging sensation in the general area of my Achilles tendon.  I'm assuming this is an Achilles injury attempting to wreak havoc on my training.  Like a good little boy, I stopped running in an attempt to stave off a full blown case of Achilles tendonitis.

After a small break, the would-be injury disappeared -- it disappeared until I decided to run again -- in which case it presented itself once again as a non-painful sensation.  I really don't know how to describe it other than to say that it doesn't hurt although at one point, I think I might have felt a slight burning sensation but I am hyper-sensitive to just about anything now.
