[Supplementary Discussion]
Rouci (Fleshy Spur/Ingrown Nail), also known as onychocryptosis or pterygium unguis, grows between the toes. Its shape resembles a hard callosity (callus), adhering to the surrounding flesh, causing dull pain akin to needle pricks. It is caused by tight shoes and socks rubbing against each other.
