When your finger or toe nails start to get a fungal infection. Try soaking them in an apple 🍎 cider vinegar soak and some warm water.
If this does not work after a few soaks and your issue gets worse. It usually doesn’t just go away it gets worse. You may want to see a dermatologist.
Sometimes this happens from germs getting a manicure or pedicure at a nail salon or spa. It has happened to me. It’s NOT pretty it isn’t fun. And sometimes it just happens to one or a few toes on your feet. Weird but true.
