Question) What is the new line I see on my thumbnail?
2025.12.09 08:11
Lately, I've been getting very anxious about a distinct vertical line on my thumbnail. I haven't hit it anywhere, and I don't know if it's due to nutritional deficiencies or stress, but I'm getting even more anxious because I don't know the exact cause. It's not particularly painful, but it's noticeable, so I keep looking at it. Do these things usually go away on their own? I'm wondering if I should see a doctor. If you've had a similar experience, please advise.
