Hey y’all, as I was playing with my cat, I noticed she had blood on her left bottom paw, and the nail appeared bent/crooked (as shown in photo).

Then I went to check her again a few minutes later, and found a loose nail. But I don’t think it came from the same paw. Is this an ingrown issue? When I press on her paw to check, she kinda groans and hisses at me. Is this something that can fix itself over time? Or must a vet be seen for an emergency?
