My big toe used to grow a double toenail. As soon as it would grow out, it would start again. Many years ago, a doctor took pictures of it to publish in a medical paper. But now they seem to be more common. Don't believe me? Here are pictures of it in different growth stages.
What made me think of this now? Well, I went to my podiatrist yesterday, for the first time since Covid. I have fungus on NINE toes!! Phil has had it on one toenail formany years, and lost his entire nail several times. The doctors say that even if they remove your entire nail, it can still come back!
