Ever been skiing and noticed your toenail had turned black and incredibly painful at the end of the day? Was the entire nail black or only the base?  "Skier's toe" is a common and often very frustrating injury from skiing.

The medical term is a subungual hematoma, which simply means bleeding under the nail. This can occur from a single instance of trauma like dropping something on your toe, or from small, repetitive trauma like a too-small or too-big ski boot (which allows your foot to slip back and forth, slamming your toes repeatedly).

If YOUR toenail is black and painful at the end of your ski day- do NOT wait to go in to a clinic, because the sooner you get treatment, the higher the success rate. The treatment procedure involves burning a tiny hole through the nail, which allows the trapped blood to drain. There is typically only a few drops of blood, but the pain that small amount of blood causes underneath the nail (if NOT removed) is fairly intense.

As with so many medical problems, PREVENTION is key! Make sure your ski boots fit properly- do NOT cram your foot into a friend's boots- and be sure your socks are not bunched up. Using the newer thin ski socks, rather than old school super thick ones, also helps. (Don't worry, the new fabrics keep your toes warmer, despite what it might appear.) This painful injury should NOT occur if your shoes/boots fit correctly.

BOTTOM LINE: Make sure your ski boots and socks fit properly to avoid getting skier's toe!

PS. While in experienced hands, the red-hot tip of a flame-sterilized paperclip may be used to swiftly burn a tiny hole through the nail, I would definitely NOT recommend trying this on your own after watching a youtube video for training. Among other challenges, people have been known to pass out from simply watching this procedure done...and dealing with the head injury (or other trauma) that results from someone passing out (often in a bathroom with sharp or hard counter edges) is worse than the original problem.
