At around mile 3 or so, I felt a twinge in my mid-back on the left side. Sometimes this will happen and then go away, but this one stayed...and it continued to get worse.
I made a chiro appointment at lunch today - ends up the muscles between the last two ribs had "locked up". After some cracking, massaging and electro stim, it's still hurting me - especially when I do any type of twisting action. The chiro told me to ice it this evening and by tomorrow it should feel better.
I hope so, since tomorrow I'll be on a bus for 4-5 hours on my way to New York! And tomorrow evening is a group run in Central Park with Team Run To Remember!!!
