I'm in tumbling classes right now and have been for a while but recently it started hurting to walk with my right leg cause my toe always hurt when I put it on the ground it doesn't hurt to touch my toe with my hands, it only hurts when I walk and it hurts sometimes and sometimes it doesn't I have no clue what I did to it help?

Could be a fracture or minor break, you could have sprained the muscle in your toe.

Toes don't always swell or bruise when they're injured. Especially if they've been injured before.

Have you tried wrapping it or taping it to the toe next to it? Which toe is it?

The big toe is hard to heal properly. It carries the most stress while you walk.

You MIGHT be able to find a toe split, or a rigid brace/cap sort of thing, to help support it and keep it still.
