Happily, the injury seems to be healing very nicely. Twice-daily bathing in Dettol, lots of Savlon cream, etc, seems to have kept all trace of infection away. I was able to wear slip-on, covered shoes to work on the Thursday and Friday, and the area around the cuticle seems to be repairing itself, and no trace that the nail will drop off. Whew! (I was determined not to see a doctor unless infection sprung up, either under the nail itself or deep under the damaged cuticle; I simply couldn't see what else a doctor might do for it - would it be worth the several hours of waiting for my name to be called down at the medical centre?)
I am fascinated with the human body's amazing ability to repair itself, and to remember where everything needs to go; if you'd seen my toe last week you wouldn't have been able to imagine what was needed to get it looking normal again, at least not without antibiotics, or maybe some medical glue. Certainly, although the skin near the nail had split in two places, there was nowhere to even consider putting in stitches, so I figured waiting it out was all I could do.
Today, the toe's looking almost normal again. Luckily I've been able to spend most of the week shoeless and sockless. Despite the lower Canberra temperatures at night, the days have featured glorious thong-wearing weather (that's flip flop-wearing weather for all you suddenly-horrified US readers). Getting some fresh air to my toe has definitely helped.
Rainbows are possible, even on sunny days, in Canberra!
