If you've noticed a depression in your thumb nail, you may be experiencing a condition known as nail pitting, which is characterised by small depressions or dimples in the nail. Nail pitting is often associated with nail psoriasis, but it can also be a sign of other health conditions, including ageing, dermatitis, eczema, anaemia, vitamin or nutritional deficiencies, cardiovascular issues, thyroid problems, or diabetes. In some cases, nail pitting may be caused by certain medications or treatments. While nail pitting is typically found on the fingernails, it can also occur on the toenails.
