This isn’t “everything” normal… this is a “fish eye” and it’s caused by a virus.

and the virus will penetrate deeper. Don’t say “it will go away on its own”: sometimes it does, but sometimes it deepens and becomes painful when you walk. What’s the solution? You need a dermatologist/surgeon. This is not a diagnosis, just general information. A “corn” requires a doctor to confirm it’s indeed a wart and not something else. Treatments a doctor might prescribe include: Salicylic acid: patches or a liquid that gradually dissolves the rough layer. Cryotherapy: the doctor freezes it with liquid nitrogen. Laser or cauterization: if it’s very stubborn. Prevention: Don’t go barefoot in baths/pools. Change your socks every day and let your feet breathe. If you have a wart, cover it with a plaster when you go to the pool to avoid infecting others. Important: If you have diabetes, circulatory problems, or a weak immune system, never treat it yourself. See a doctor immediately. This isn’t a medical diagnosis. If the pain is severe or worsening, consult a dermatologist or podiatrist. Does it hurt when you stand on it? Have you tried any over-the-counter medications that didn’t work?
