Vertical ridges are common and usually not a sign to worry; may become more prominent as you grow older. Horizontal ridges can mean that you have an underlying medical condition such as a respiratory disorder, lack of iron, thyroid problem, or poor circulation, or something as simple as a previous injury or is caused by certain medications.
