Please help me see if this is a pestle finger? I'm a little uncertain myself.
Condition Analysis:
From the picture, it doesn't look like a pestle finger. In addition, from your picture symptoms, consider that there may be a lack of corresponding trace elements and vitamins, such as calcium and zinc. There are corresponding vertical lines and depressions on the nails. Eat more fresh vegetables and fruits every day to supplement your own trace elements and vitamins.
Condition Analysis:
This finger doesn't look like a pestle finger. I don't know how you feel like you have a pestle finger. As the name suggests, the end of this finger is expanded, similar to a pestle. It is caused by chronic cardiopulmonary disease, not a specific disease, so you don't have to worry.
