Hi birwin,
I was curious about this and a search brought up this from a doctor, along with the disclaimer!
Definitely a great idea to bring this up at whatever next doctor's appointment you have. I found naturopathic physicians the be a great help with body balancing and knowledge of the connection between mind, body, stress, mineral rebalancing and healing.
The line of overlap or demarcation in your nail is most likely associated with a period of trauma or injury to the nail matrix. Sickness, trauma and decreased nutritional status can all damage and negatively impact nail growth. Imagine the line of overlap is the nail trying to grow longer but there is a little wall blocking the actually forward growth of the nail, so the cells topple on top of eachother. Eventually this overlap in your nail will grow out and you should have a normal, flat nail!
