My daughter is 11. When she was 4, all of the bases of her fingernails started to disappear. There was no nail growing. After a couple of months, her nails began to grow again. The doctor said it was probably from a fever she had weeks prior. Now, she has the same problem happening to her left thumb. There is a large circular area at the base of her thumb nail that is void of nail. She went to the doctor yesterday and they said they have no idea why it did that. She is healthy, but was a premature baby (32 weeks). She is also a nail biter. The doctor referred us to see a dermatologist...but that isn't for another three weeks. The area without nail is not painful.
Any thoughts?
