A fungal nail infection may not always hurt, but it can trigger unsightly discolored nails that itch, along with surrounding toes or fingers.
The American Academy of Dermatology says symptoms of a fungal nail infection include:
- Nails that become yellow or brown, starting at the tips and spreading across the nails. Such nails may crumble or split.
- Accumulation of debris underneath the nails. Eventually, the nails can detach as they pull away from the nail beds.
- A powdery, soft or dry texture to the nails.
