Common Toenail Question

I get questions by email all the time. Toenail questions are quite common, so I thought I’d post this one. Here’s the question.

“I am emailing you because I have a 50K trail race this Saturday and for some reason I am just starting to get pressure from under my large toenail. It is in its early stages and my nail has not turned black yet, but it is starting to be uncomfortable. At what point do I decide to puncture thru my nail and lance the fluid under the nail? Also, if I should be lancing the fluid, what are your thoughts of using a really thin and clean drill bit (turned by hand) to get thru the toenail? I lost a toe nail once before and tried using a really hot paper clip and needle, but I had a hard time getting all the way thru my toe nail. Any help and advice you can give me would be much appreciated… thank you!”

The answer is pretty straightforward.

Can you recall any nailbed trauma? Once fluid is underneath the nail, the pressure becomes painful You’ll know. If you can see the fluid from under the tip of the nail, lance it there. A drill bit works better than a paperclip. Be forewarned that as it goes through the nail, it can go into the soft tissue underneath, so go slowly. Then press on the nail to expel as much of the fluid as possible. Cover with a Band-Aid for now (tape on race day) but don’t plug the hole with ointment, as it will still need to drain for a few days.

Relieving fluid from underneath a toenail is a simple skill that every runner should know how to perform – just in case. It could be on one of your toes, or the toe of a friend. If you have ever experienced the intense pain of a black toenail with blood or fluid underneath, you’ll appreciate knowing how to fix it.
