Keep a eye on it: Chances are if you have two thin lines under your nail and it wasn't there two days ago then you probably did something. It does not have to be an injury. Did you paint or expose your hand to something? Wash the wheel wells? If it persists, is painful, gets red, call your doctor.

Blisters under: Toenails are quite common in sports participants. If you're able to drain it, apply a topical antibiotic and wrap it in a band aid, that's about the best you can do short term. You might want to check on the size of the soccer boots. If too small, they can be making things worse. Also, i hope the coach/trainer has them wearing running shoes for the pure running workouts.

She might try wearing two pair of socks on each foot and see if that helps. This was something I was taught back in high school by my coach and it worked for me. ( to prevent the blisters, not treat them.)

Several Options: If you recentry injured the area of concern, then a tendon injury is possible. If not. You could have developed a ganglion cyst which tends to be common in the wrist and hand. I would have a physician examine it to find out what would be the next step.
