New fingernail growing under old fingernail?
So my 2 year old was showing his owie on his hand, and upon a closer look, he appears to have a new fingernail growing underneath his old fingernail. The old fingernail is barely hanging onto his finger, and I can clearly see a second nail underneath the original nail, but any sort of contact with the finger causes him great discomfort. It appears as if the same process is going on to a finger on the other hand as well. Any ideas what this could be?
