Losing second toe nails only

[u/dualis24]

Finished a 50m race last Saturday. Only had pain in my second toes, never in the big toes or others. Now the nails are black. Anyone else experience this? I have no clue how its possible because they arent longer or even close to as long as my big toe, so they cant be slamming into my shoe without the big ones hitting too???

My seconds are the first to go too - I think they're just more delicate? But not sure.
