My back is feeling better. It's past the "knife sticking in my back" stage and into the "wow I shouldn't have done 20 hours of Sweatin' To the Oldies" sore muscle stage. My cold also seems to be dissipating; I can now breathe (mostly) through my nose and I'm no longer going through half a box of Kleenex per day. I do seem to have picked up a rather annoying cough and my temperature has reached 100°F. I have a nasty habit of colds turning into bronchitis or worse; I hope this isn't the case again.
