Noticing a dark line on your thumb can understandably raise concerns, especially when linked to discussions about more serious conditions. It’s important to ensure that your worries are addressed while also putting things in perspective.

Dark lines on nails, like the one you’re seeing, can be caused by several things, including:

1. Normal Variations: Sometimes, dark lines can be benign and related to simple factors like minor trauma (even unnoticeable) or natural pigmentation changes.

2. Fungal Infections: These can sometimes create discoloration without causing pain.

3. Dermatological Conditions: Some skin conditions might lead to dark lines but are usually not concerning.

Although the line hasn’t worsened or caused pain, it’s good to be proactive with your health. Here are prioritized steps to consider:

Next Steps:

1. Monitor Changes: Keep an eye on the line over the next few weeks. Note any changes in color, size, or texture. If it grows or you see other concerning symptoms, that will guide your next steps.

2. Check with Your Friend: Since you mentioned your friend has a similar line, it might be worthwhile to compare notes. However, you should still consider personal variations because everyone's body is different.

3. Document Observations: Start a diary to log any changes you notice, alongside details like when you first saw it and any activities that might relate to its appearance.

4. Consult a Doctor: If the line changes significantly or if you develop other symptoms, such as changes in nail appearance or discomfort, it would be wise to seek a professional opinion. A dermatologist will provide the best assessment for nail conditions.

It's good that you're taking an interest in your health! Keeping things in perspective while remaining attentive to changes is key. Remember, most changes in the nails tend to be harmless, but you know your body best. If you feel uncertain at any point, trust your instincts to seek help.
